Abstract:

Pests and diseases are recurring issues in the cultivation of forest plant seedlings, as they can reduce seedling quality and lead to economic losses due to seedling mortality. Identifying the types of pests and diseases is crucial for implementing more effective, efficient, and environmentally friendly control measures to maintain seedling quality. The methodology used in this study was a field survey with direct observation of seedlings affected by pests and diseases. Data collected included the types of pests and diseases observed in various seedlings, such as Annona muricata, Albizia saman

Abstract:

In Japan, rice seed are immersed in pesticide solutions to prevent seedborne diseases that attack greenhouse seedlings. However, disposal of large quantities of waste pesticide solutions after treatment is costly. As an alternative treatment, bacteriophages (phages) that are highly specific to the target bacteria are considered as potential biocontrol agents. Here, we isolated three phage strains that lyse Burkholderia glumae and B. plantarii, the causative pathogens of seedling rot and seedling blight, respectively. Two phages could lyse both bacteria and clearly suppress these diseases. One

Abstract:

Good oil palm seedlings planted in Malaysia can enhance the nursery area, the economy, and rural employment. Nitrogen (N), potassium (K), \and magnesium (Mg) deficiencies in oil palm seedlings could have an adverse effect on growth and seedling quality. In contrast, excess fertiliser in oil palm seedlings could reduce macronutrients and soil organic matter levels. Moreover, various diseases appear on the oil palm seedling leaves resulting from nutrient deficiencies. Oil palm seedlings with nutrient deficiencies were more susceptible to pathogens and diseases than healthy oil palm seedlings. Th

Abstract:

Hydroponic culture systems are subject to high risks of diseases caused by zoosporic plant pathogens. Control is generally difficult because of the rapid spread of zoospores in the nutrient solutions. In Japan, tomato and eustoma, which are cultivated using the D-tray and nutrient film techniques, respectively, are susceptible to diseases caused by Pythium aphanidermatum and P. irregulare. We used loop-mediated isothermal amplification to identify potential contamination sources of these two pathogens by monitoring their presence in the water supply wells, seedling terraces, nutrient solutions

Abstract:

Cotton production using conservation tillage practices has increased in the past decade. Most studies involving reduced tillage have shown a reduction in plant populations, which has been attributed to seedling diseases. Although most of these studies have focused on no-till production, cotton planted in the mid-south is often planted using stale seedbeds. The objective of this research was to compare the effect of stale seedbed production and conventional tillage with and without in-furrow fungicides on the incidence and severity of seedling diseases. Tillage systems were established in the f

Abstract:

Automatic grafting and cutting machines can be employed to satisfy the increasing demand for seedlings without soil-borne diseases in a short period. The main approach used to feed seedlings for automatic grafting and cutting machines is artificial, which limits the improvement of grafting and cutting machine productivity. The separation system with a subdivision air stream can stably feed seedlings for cutting and grafting machines; however, the separation efficiency is low when a few seedlings are in the separator. To solve this problem, a feedback monitoring device with a photosensitive sen

Seedling resistances to stem rust, leaf rust and stripe rust were evaluated in the 37th International Triticale Screening Nursery, distributed by the International Wheat and Maize Improvement Centre (CIMMYT) in 2005. In stem rust tests, 12 and 69 of a total of 81 entries were postulated to carry Sr27 and SrSatu, respectively. When compared with previous studies of CIMMYT triticale nurseries distributed from 1980 to 1986 and 1991 to 1993, the results suggest a lack of expansion in the diversity of stem rust resistance. A total of 62 of 64 entries were resistant to five leaf rust pathotypes. In

This study investigated the control of foliar fungal diseases and growth promotion of Camellia oleifera seedlings in coastal reclaimed land through the use of Bacillus licheniformis MH48. B. licheniformis MH48 can produce lytic enzymes chitinase and β-1,3-glucanase that can inhibit foliar pathogens by 37.4 to 50.5%. Nevertheless, foliar diseases appeared in the seedlings with bacterial inoculation, and their survival rate decreased because they were unable to withstand salt stress. However, B. licheniformis MH48 significantly increased the total nitrogen and phosphorus contents in the soils th

Abstract:

Sugar beets are susceptible to a number of seedling and root rot diseases that constrain profitable sugar beet production. Since numerous environmental and cultural factors may cause symptoms that could be confused with symptoms caused by these pathogens, it is important to correctly identify and differentiate between various diseases and problems to effectively manage them. The goal of this guide is to assist in the identification and effective differentiation of various seedling and root rot diseases common to sugar beet. Accepted for publication 7 June 2006.

Bacterial attack is a serious agricultural problem for growth of rice seedlings in the nursery and field. The thionins purified from seed and etiolated seedlings of barley are known to have antimicrobial activity against necrotrophic pathogens; however, we found that no endogenous rice thionin genes alone are enough for resistance to two major seed-transmitted phytopathogenic bacteria, Burkholderia plantarii and B. glumae, although rice thionin genes constitutively expressed in coleoptile, the target organ of the bacteria. Thus, we isolated thionin genes from oat, one of which was overexpresse

Seedlings were counted weekly in quadrats established in winter wheat stubble at Akron, CO. Seedling emergence varied among years, which was caused by erratic seasonal precipitation. Producers delay planting of winter wheat to reduce downy brome density in the crop, but in only 1 yr out of 6 would producers have benefited from this control strategy. Furthermore, delayed planting has negative crop consequences: less grain yield and more susceptibility to plant diseases and wind erosion b
