Abstract:
Gibberella zeae, Fusarium verticillioides and F. subglutinans are the most important causes of Fusarium stalk rot in corn (Zea mays L.). Gibberella zeae also causes fusarium head blight in wheat (Triticum aestivum L.) and gibberella ear rot in corn. The objectives of this study were to investigate prevalence of Fusarium species in the stalks of seed corn over time and to investigate the influence of sampling time and internode position on Fusarium spp. and G. zeae, particularly. Fusarium subglutinans and G. zeae were the most frequently recovered species from asymptomatic host tissue and from pink discoloration on stalks, respectively. More G. zeae was isolated from the basal internode of stalks than from the higher ones closer to harvest time. Other species isolated from seed corn stalks over time included F. verticillioides, F. oxysporum, F. sporotrichioides and F. equiseti. A similar spectrum of Fusarium species was identified from corn ears and from winter wheat across southwestern Ontario. Key words: Zea mays L., Fusarium spp.

Abstract:
To support large-scal e corn exports by the Minister of Agriculture, production is needed. One way is by hybridizing corn plants to produce new corn plants with high production. This study aims to determine the results of crosses between sweet corn and sticky corn. Reinforcement Sidoarjo with a height of sea level ± 7m in May to August 2018. This research was carried out descriptively with 2 types of crosses of sweet corn as female parent and glutinous corn as male parent (TK) and glutinous corn as female parent and sweet corn a s male parent (KT), which is repeated 4 times then continued with unpaired T Test and the usual percentage to determine the difference between TK and K The variables observed were ear weight, seed color, seed shape, and dry weight per 100 seeds. The resu lts showed that crosses gave rise to 3 color variants namely white, yellowish white and yellow. With a color ratio of 3: 1 in the TK treatment and 1: 3 in the KT treatment. Crosses of sweet corn and sticky corn also produced 2 different forms of corn, namely wrinkles and solid forms with a total percentage of 16,625% in the form of wrinkles and 83,375% in round shape.

Abstract:
Field experiments were conducted from 1987 to 1990 to investigate the combination of cultural and chemical methods for control ofAmaranthusspp. in corn. The tolerance of corn hybrids to herbicides or herbicide combinations was dependent on application rate. The early season threshold level for a mixed population ofAmaranthusspp. occurred 3.5 wk after emergence. Density ofAmaranthusspp. from 155 to 495 plants/m2caused corn yield reduction of 50%. A quadratic model was derived relating percentage of yield reduction vs. duration of weed competition. The results emphasize the importance of using herbicides, cultural practices, and competition thresholds for an integrated weed control approach ofAmaranthusspp. in corn.

Abstract:
Corn is a crop of great importance in the world since it constitutes a basic component of the diet of the population; a production of 1026.61 million tons was estimated during the present year. Currently, there are many theories about the wild ancestors of corn, being Proto-Confite Morocho one of the primitive races in Peru, which is attributedas the ancestor of numerous native varieties. Therefore, knowledge of its genetic constitution is important since it gives us the possibility of finding phylogenetic affinities and indicators of systematic classification. The present study was carried out with the purpose of elaborating the karyotype of Zea mays ssp. mays ‘native corn’ Proto-Confite morocho and determine the number and morphology of the chromosomes. Corn seeds from the province of Virú, La Libertad, Peru, were used, while the experimental phase was developed in the Laboratory of Geneticsand Molecular Biology at the National University of Trujillo, where metaphase plaques were obtained, selecting the best to perform the karyotype. It was concluded that the Zea mays ssp. mays ‘native corn’ Proto-Confite morocho presents 3 pairs of chromosomes ( 4, 4’, 8, 8’, 10, 10’) submetacentric and 7 pairs of chromosomes (1, 1’, 2, 2’,3, 3’, 5, 5’, 6, 6’, 7, 7’, 9, 9’) metacentric, which average size are between 4.16 and 1.88 μm.

Abstract:
Initial corn (IC) in a replant situation, which is surviving corn from the initial planting, as well as volunteer corn from the previous season, is a competitive weed, but little is known regarding the effect of IC density on grain yield of desirable replant corn (RC). Field trials were established in central and northeast Missouri during 2008 to 2010 to determine the impact of IC on the leaf chlorophyll, stalk diameter, and grain yield of RC. Glyphosate-resistant RC was planted in 76-cm rows, with hybrid glyphosate-resistant IC established for season-long competition between rows at densities of 0 to 8 plants m−2. At vegetative growth stages with six and eight leaf collars and at tasseling (V6, V8, VT), RC leaf nitrogen levels were reduced by 5 to 30% in the presence of IC at densities of one to eight plants m−2compared with control plants lacking competition. Stalk diameters of RC at the VT growth stage were reduced from 8 to 30% by IC as densities increased from 0.5 to 8 plants m−2. Grain yield of row corn was reduced by IC, with yield losses ranging from 7 to 81%. Growth rate and biomass accumulation of hybrid and volunteer corn from V2 to VT were compared in the greenhouse to determine if competitive potential was similar. The second filial generation (F2) of corn from hybrid (DKC ‘63-42′) corn was collected from a field in central Missouri and southeastern Nebraska. There were no statistical differences found in growth rate or biomass accumulation between hybrid and F2corn up to VT, although F2plant biomass was numerically (up to 41%) lower at numerous growth stages. Hybrid corn is likely to be equally or more competitive with RC than volunteer corn. This research documents that in areas where IC remains among replanted corn, the IC has a negative impact at all densities evaluated.

Full text
Abstract:
Glyphosate was evaluated as a preharvest treatment for enhancing corn kernel dry down and quackgrass control. Glyphosate at 0.4, 0.8, 1.3, and 1.7 kg ae/ha was applied to corn before physiological maturity (kernel moisture 44 to 47%) and at physiological maturity (kernel moisture 35 to 39%). Three weeks after treatment, grain moisture of plants treated at physiological maturity was 2.3 to 6.9% less than that of plants treated before physiological maturity which was 2.2 to 5.5% less than that of untreated plants. Glyphosate did not increase corn kernel drying effectively under high humidity conditions. Glyphosate applied to pre-physiologically-mature corn controlled quackgrass 49 to 64% in the fall of 1984 and 69 to 91% in the fall of 1985. None of the glyphosate treatments reduced corn yield. Glyphosate applied preharvest above the corn canopy may increase the rate of corn kernel drying and may control fall quackgrass in the northern corn belt.

Abstract:
Corn hybrids and inbreds were ranked for their relative tolerance to soil-incorporated clomazone, as assessed by the level of discoloration injury in the greenhouse. Inbred W117 was the most tolerant corn line tested. Some corn lines were affected similarly by clomazone. Inbred A619 was in the most susceptible group. Clomazone injury to A619 (susceptible) and W117 (tolerant) corn was similar when the clomazone rate was 10-fold greater on W117 than on A619. The distribution of corn lines on a sensitivity scale was of limited range; the distribution of hybrids on this scale was a single symmetrical peak. Changing the growth temperature or soil composition would change the absolute level of corn injury caused by a rate of clomazone but did not change the relative ranking of the corn lines in the test. A subset of the greenhouse-tested corn lines also was evaluated in several field locations. The tolerance of corn in a given field was highly (P<0.005) correlated with tolerance in the greenhouse; however, the absolute levels of injury differed among locations. The tolerance of- hybrids of known pedigree was highly (P<0.0002) correlated with the tolerance of the parent inbreds, indicating this trait was inherited.

Full text
Abstract:
Corn cultivars differed in their response to imazaquin applied from 35 to 280 g ai/ha, as measured by shoot length. No cultivar was tolerant to all imazaquin application rates. There was less corn injury from imazaquin in studies conducted during the second and third years of research than in the first year. Preplant-incorporated applications caused significantly more injury than preemergence applications in two out of three studies. Lack of rainfall in 1985 and 1987 may have limited movement of imazaquin in the soil profile, which resulted in preemergence applications of imazaquin, causing very little corn injury. In all years of research, 35 g/ha of imazaquin incorporated in the top 6 cm of the soil profile resulted in 17 to 33% reduction in corn height 28 days after planting, when averaged across all the corn cultivars. Significant yield reductions (LSD = 0.10) of 45, 19, and 18% occurred in 1987 from preplantincorporated applications of 140, 70, and 35 g/ha, respectively, which had reduced corn height 46, 23, and 19%, respectively, when measured 28 days after planting.

Abstract:
The cultivation of alternative crops has an important role in world agriculture. Their market share is continuously growing in the food industry sector. In the present study, we show the cultivation and breeding perspectives of ornamental and blue corn. There exists possibility to cultivate ornamental corn in Hungary. There are many cultivars of ornamental corn, with various kernel colors, husks, stalks and leave colors. Blue corn is unique among other corns. Blue corn higher in protein, iron and zinc than commercial dent corn. Pests affective ornamental and blue corn are the same as those of other commercial corns. Ornamental and blue corns need to be grown a minimum of 500 m away from commercial yellow dent corn to minimize any cross pollination which may result in off-color kernel. Our aim in the presentation of this review was to broaden Hungarian literature.

Abstract:
Nine sweet corn cultivars were evaluated to identify cultivar sensitivity to primisulfuron in four field studies, conducted over a 2-yr period. Response to primisulfuron varied, depending on cultivar and application dose. DelMonte 2038 was highly sensitive to primisulfuron resulting in very severe injury and, in most cases, the death of all plants at both locations, each year. At Exeter in 1998 and 1999, injury was slight with no plant height or yield reductions on other cultivars. At Simcoe in 1998 and 1999, five other cultivars showed visual injury of 10% or greater at 50 g ha–1 of primisulfuron. However, in most cases, this did not result in a significant plant height or yield reduction. SS Jubilee Bt showed a yield reduction but only in 1998 at Simcoe. Three cultivars, CNS 710, GH 2690 and Reveille, were classified as fully tolerant to field applications of primisulfuron at 25 g ai ha–1 with little or no risk of injury.

Abstract:
Greenhouse studies were conducted to determine the effects of herbicide, herbicide rate, genetic variability, and soil moisture content on the tolerance of corn seedlings to two chloroacetanilide herbicides. Alachlor and metolachlor were applied preemergence at 2.2, 3.4, 4.5, and 6.7 kg ha-1to 10 Great Lakes corn hybrids. Metolachlor appeared to be less injurious at the low rate and more injurious at the high rate than alachlor. Injury among the 10 hybrids tested varied significantly. Some of the hybrids appeared to tolerate alachlor more, while others tolerated metolachlor more indicating that even in a limited number of hybrids there was a spectrum of response. Six levels ranging from 8% to 22% soil moisture were evaluated for their effect on alachlor and metolachlor injury to corn seedlings. The herbicide injury ranged from no injury at the lowest soil moisture level to about 70% at the highest soil moisture level with 4.5 kg ha-1application rate of alachlor or metolachlor.

Injury to the hybrids increased as nicosulfuron rate increased. In 1988, some of the hybrids were stunted slightly by all of the herbicide rates, but within a hybrid there was no significant difference among herbicide rates. In 1989 none of the hybrids, including Jubilee, was stunted by even 140 g ai ha–1nicosulfuron compared with the corresponding check. Effects of nicosulfuron on yields of the eight hybrids in 1988 and in 1989 are best described by a quadratic regression equation.

Abstract:
An experiment was conducted at five locations in North Carolina to compare management systems utilizing glufosinate applied postemergence (POST) in glufosinate-resistant corn with standard systems of metolachlor plus atrazine preemergence (PRE) or nicosulfuron plus atrazine POST Glufosinate alone and both standard systems controlled common ragweed and prickly sida at least 98%, whereas sicklepod control was < 20% late in the season. Late-season control of common lambsquarters, smooth pigweed, pitted morningglory, and tall morningglory was generally less with glufosinate alone than with the standard systems. However, late-season control of common lambsquarters, smooth pigweed, pitted morningglory, tall morningglory, and sicklepod by mixtures of glufosinate plus atrazine was at least 99, 100, 89, 93, and 81%, respectively, and was equal to or greater than control by either standard. Broadleaf signalgrass, large crabgrass, and fall panicum were controlled similarly by glufosinate and the standards. Goosegrass control by glufosinate was similar to control by nicosulfuron plus atrazine, but it was less than control by metolachlor plus atrazine. Metolachlor applied PRE or atrazine mixed with glufosinate increased goosegrass control to that achieved with metolachlor plus atrazine. Mixing atrazine with glufosinate did not affect fall panicum control, but metolachlor PRE followed by glufosinate controlled fall panicum as well as the standards. Cultivation or ametryn applied at layby increased control when PRE or POST herbicides alone controlled weeds less than about 90%. Ametryn was generally more effective than cultivation. Glufosinate POST followed by ametryn at layby controlled sicklepod > 90% and other species > 95% late in the season. Corn yield and net returns were similar in the glufosinate and standard systems.

Abstract:
Corn (Zea maysL.) can be injured by carry-over of trifluralin [2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl) benzenamine] in the soil from one crop year to the next. Factors influencing corn tolerance to carry-over concentrations of trifluralin in the soil were studied in controlled-environment chambers and greenhouse experiments. For several hybrids, greater injury occurred at low than at high temperatures. This injury was especially evident for ‘Pioneer 3320’ and ‘Pioneer 3572’ when the soil moisture was at 100% field capacity. Addition of phosphorus fertilizer appeared to have no influence upon trifluralin injury but did interact with alachlor [2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl)acetamide]. Alachlor plus trifluralin injured corn in an apparently additive manner. Significant differences were found in genetic tolerance of corn to trifluralin within a group of hybrids. Tolerance of specific hybrids to trifluralin was altered by environmental conditions.

Abstract:
Volunteer corn (Zea maysL. # ZEAMX) is a troublesome weed in soybeans [Glycine max(L.) Merr.] grown in the Corn Belt. Field studies were conducted in 1983 and 1984 at Champaign, IL, to determine the soybean growth and yield parameters affected by volunteer corn interference. Soybean yield was inversely and linearly related to volunteer corn clump density, with yield losses reaching 25% at 5380 clumps/ha (10 plants/clump). Volunteer corn clumps of 1, 4, 7, and 10 plants reduced soybean yields by 6, 16, 21, and 22%, respectively, at a density of 5380 clumps/ha. Treatments of either the butyl ester of fluazifop {(±)-2-[4-[[5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy] propanoic acid} or glyphosate [N-(phosphonomethyl)glycine] were applied at various dates between 2 and 12 weeks after soybean emergence (WAE) to a volunteer corn infestation of 5380 clumps/ha (10 plants/clump). Volunteer corn caused soybean yield losses of 2, 6, 12, 19, and 27% when herbicides were applied at 2, 4, 6, 8, and 10 WAE, respectively. Volunteer corn interference reduced soybean seed yield, plant dry weight, pod number, seed number, leaf fresh weight, and leaf area index, within 40 cm of a clump of 10 volunteer corn plants. A clump of 10 volunteer corn plants reduced soybean pod number/plant within a radius of 86 cm.

Abstract:
Background: Corn silk, a traditional Chinese herbal medicine in China, has been used to remedy nephritis, hepatitis, measles, hyperglycemia, tumor, etc. In this study, flavonoid monomers in corn silk were isolated and identified. This study could serve as a basis for determining the curative effects of these monomers on human diseases. Method: Corn silk flavonoids were extracted using 80% (v/v) ethanol and isolated by repeated polyamide column and Toyopearl HW-40 column chromatography. Corn silk flavonoids were identified by UV spectroscopy, liquid chromatography/mass spectroscopy, and nuclear magnetic resonance spectroscopy. Results: Two C-glycoside flavones, namely, ax-4″-OH-3′-methoxymaysin and a 3′-methoxymaysin isomer, were isolated from corn silk and identified. Conclusion: The two C-glycoside flavones were successfully isolated from corn silk and identified. This study is the first to report 3′-methoxymaysin in corn silk.

Abstract:
There is little published information on the sensitivity of sweet corn to the PRE and POST application of isoxaflutole + cyprosulfamide. Four field trials were conducted during 2010 and 2011 in Ontario, Canada, to determine the sensitivity of ‘Merit’, ‘GH 4927’, ‘BSS 5362’, and ‘GG 741’ sweet corn hybrids to the PRE and POST application of isoxaflutole alone or in combination with cyprosulfamide. Isoxaflutole applied PRE or POST at 105 and 210 g a.i./ha caused as much as 12% visual injury, 18% reduction in height. and 24% reduction in marketable yield of some sweet corn hybrids evaluated. Isoxaflutole + cyprosulfamide applied PRE or POST at 105 and 210 g·ha−1 caused up to 7% initial injury in some sweet corn hybrids but the injury was transient with no effect on sweet corn height, cob size, and yield. Isoxaflutole applied POST was more injurious to sweet corn than when applied PRE; however, there was no differences in sweet corn injury between the PRE and POST applications of isoxaflutole + cyprosulfamide. Based on these results, there is potential for use of isoxaflutole + cyprosulfamide applied at 105 g a.i./ha in ‘Merit’, ‘GH 4927’, ‘BSS 5362’, and ‘GG 741’ sweet corn hybrids.

Abstract:
The maize (Zea mays L. ssp. mays) has several related species, called teosinte, which are distributed in various subspecies of Zea and other genera. Among the different types of corn, sweet corn shows a great potential for human food. This type was originated from mutations, which increased the amount of polysaccharide in the endosperm. In Brazil there are populations of sweet corn, common maize and teosinte, however, little is known about their genetic variability. Hence, the aim of this present paper was to analyze the genetic variability in two populations of sweet corn (BR 400 and BR 402), two common corn (Pampa and Suwan) and teosinte, using microsatellite markers. The results showed a low intra-population genetic variability in populations of maize, and high variability for the population of teosinte, suggesting that the maize populations may have limitations in future cycles of breeding.

Abstract:
A computer model which selects least cost herbicide programs given a minimum desired level of weed control could provide growers with economical weed management options. Using an integer programming approach, a herbicide selection model was developed for corn production under Pennsylvania conditions. Models for three rotations (corn-soybean, corn-corn, and corn-alfalfa) under three tillage systems (conventional tillage, reduced tillage, and no-till) that evaluated 21 soil-applied and 13 postemergence herbicide options for 24 weeds were developed. Each model minimizes the cost of a herbicide program subject to a desired level of weed control. By selecting the weed species to be controlled and the level of control desired, customized herbicide programs can be generated. The models can also be used to evaluate the cost of changing the level of control desired for an individual weed species or set of weeds.

Abstract:
Effects of wild proso millet interference with irrigated corn were evaluated in Nebraska and Colorado over a 2-yr period. Corn yield reductions ranged from 13 to 22% from a wild proso millet density of 10 plants m–2. As density increased, corn yield reduction could be predicted with a rectangular hyperbola regression model. Ten wild proso millet plants m–2growing with corn produced 4200 to 6200 seed m–2. Corn yields were reduced 10% at one location if wild proso millet removal was delayed 2 weeks after corn planting. If removal was further delayed until 6 weeks after corn planting, corn yield reductions at the two locations ranged from 16 to 28%.

Abstract:
Season-long interference of shattercane, giant foxtail, common cocklebur, and common lambsquarters in corn was evaluated in the field at weed densities from 0.4 to 13.1 plants or clumps/m of corn row during 1985, 1986, and 1987. Corn seed yields decreased linearly with increases in the density of clumps of 2 to 3 shattercane plants and 5 to 8 giant foxtail plants, reaching 22% yield loss at 6.6 shattercane clumps/m of row and 18% yield loss at 13.1 giant foxtail clumps/m of row. Increases in common cocklebur density caused corn yields to decrease curvilinearly in 1985 with a maximum predicted yield loss of 27% occurring at a density of 4.7 common cocklebur plants/m of row. In 1986 and 1987, yields decreased linearly as common cocklebur density increased to 6.6 plants/m of row, where a 10% yield loss was observed. Common lambsquarters reduced corn yields only in 1985. In this year, yields decreased curvilinearly with increasing weed density, resulting in a maximum yield loss of 12% at 4.9 common lambsquarters plants/m of row. Corn yields averaged 11600 kg/ha when grown without weed interference in these experiments.

Abstract:
Field studies were conducted in 1989 and 1990 to determine the potential interaction of terbufos and nicosulfuron on corn. Terbufos applied in-furrow at planting interacted with nicosulfuron applied POST to cause significant injury 25, 30, 40, 50, and 60 d after planting in 1989 and 1990. Injury decreased significantly when nicosulfuron was applied at later growth stages of corn. Plant population was not affected by terbufos and nicosulfuron regardless of the growth stage of corn at application of nicosulfuron in either year. Corn ear number and grain yield in 1989 and 1990 were lower in plots treated with terbufos at planting and nicosulfuron applied at the three leaf stage than in plots treated with only nicosulfuron. There were no differences in the height of corn, ear number, or grain yield when nicosulfuron was applied at the seven-leaf stage regardless of terbufos application in 1989 or 1990.

The results showed that growth decreased by (16.7, 48.63 and 23.56%), photosynthetic pigments decreased by (10.18, 22.38 and 10.9%) and total-N decreased by (30.0, 27.27 and 13.64%) in Zea, Hordeum and Lupinus, respectively as compared to control. Proteins profile in shoots of tested plants revealed qualitative and quantitative changes. Co-cultivated Zea with Hordeum and Lupinus treated with lead and zinc improvement all parameters. The evidences provided by this experiment indicated that Corn acts as an effective accumulator to zinc and lead.

Abstract:
Redroot pigweed is a major weed in corn throughout Ontario. Field experiments were conducted at two locations in 1991 and 1992 to determine the influence of selected densities and emergence times of redroot pigweed on corn growth and grain yield. Redroot pigweed densities of 0.5, 1, 2, 4 and 8 plants per m of row were established within 12.5 cm on either side of the corn row. In both years, redroot pigweed seeds were planted concurrently and with corn at the 3- to 5-leaf stage of corn growth. A density of 0.5 redroot pigweed per m of row from the first (earlier) emergence date of pigweed (in most cases, up to the 4-leaf stage of corn) or four redroot pigweed per m of row from the second (later) emergence date of pigweed (in most cases, between the 4- and 7-leaf stage of corn) reduced corn yield by 5%. Redroot pigweed emerging after the 7-leaf stage of corn growth did not reduce yield. Redroot pigweed seed production was dependent upon its density and time of emergence. The time of redroot pigweed emergence, relative to corn, may be more important than its density in assessing the need for postemergence control.
