Today, chemical plant protection methods are based on the safe use of pesticides. Environmental and toxicological effects are taken into account. To expand the possibilities of pest control, diseases and weeds, in the cultivation of crops, use tank mixtures that contain two or three active substances. In the preparation of mixtures take into account the processes of interaction of components and timing of application of drugs. In addition, this technique is one of the elements of the strategy to overcome the resistance of pests to insecticides, pathogens — to systemic fungicides, weeds — to he

Pistachio (Pistacia vera) was successfully introduced into California and initially touted as a tree nut crop with no disease or insect pests. Unfortunately, these expectations were dashed as a number of diseases and pests followed commercial plantings, making plant protection practices integral to production. Verticillium wilt (Verticillium dahliae) devastated early plantings but is now controlled with the use of resistant rootstocks. Botryosphaeria blight (Botryosphaeria dothidea) and alternaria late blight (Alternaria alternata) are recently arrived foliar fungal diseases that blight fruit

The basic harmful effect of weeds is reflected through the competitiveness of water, nutrients and light. Weeds generally have low nutritional value, unpleasant smell and taste, and also affect the quality of alfalfa seeds.

By 2050, the world population is likely to be 9.1 billion, the CO 2 concentration 550 ppm, the ozone concentration 60 ppb and the climate warmer by ca 2°C. In these conditions, what contribution can increased crop yield make to feeding the world? CO 2 enrichment is likely to increase yields of most crops by approximately 13 per cent but leave yields of C4 crops unchanged. It will tend to reduce water consumption by all crops, but this effect will be approximately cancelled out by the effect of the increased temperature on evaporation rates. In many places increased temperature will provide opp

Pesticides are widely used in agricultural production to prevent or control pests, diseases, weeds, and other plant pathogens in an effort to reduce or eliminate yield losses of cotton crop and maintain high product quality. Because of high biological activity, and in some cases, long persistence in the environment, pesticides (pyrethroids, carbamate, oganophosphate, organochlorines) may cause harmful effects to human health and to the environment. Occupational exposure to pesticides often occurs in the case of agricultural workers in open fields and greenhouses. Farmers who perform spray acti

ABSTRACT The nutritional value of carrot is determined by the content of total sugars and monosaccharides, carotenoids and vitamins, including vitamin C, in its roots. In 2009-2011, field experiments were carried out concerning the effect of biostimulating preparations applied during the carrot vegetation period on selected nutrients of its roots (total sugars, monosaccharides, carotenoids and vitamin C). Two biostimulants were foliarly applied in doses of 2 or 3 L ha-1 on various dates. Kelpak SL and Asahi SL: one, two or three applications; where, second and third applied at 2-week interval,

Biodiversity is adversely affected by the growing levels of synthetic chemicals released into the environment due to agricultural activities. This has been the driving force for embracing sustainable agriculture. Plant secondary metabolites offer promising alternatives for protecting plants against microbes, feeding herbivores, and weeds. Terpenes are the largest among PSMs and have been extensively studied for their potential as antimicrobial, insecticidal, and weed control agents. They also attract natural enemies of pests and beneficial insects, such as pollinators and dispersers. However,

From various aspects of life both health, aesthetics, environment and the field of farming, weeds can interfere with natural habitat and beauty.

The globalisation of trade has moved pests out of natural ranges, creating damaging epidemics in new regions. Climate change has extended the range of pests and the pathogens they vector. Resistance to agrochemicals has made pathogens, pests, and weeds more difficult to control.

Long-term field trial data was used to assess the impact of different pests on grain yield. In the absence of pesticides, fungal diseases caused the largest annual yield-reduction in spring wheat and spring barley, 500 kg ha−1 on average. Converting yield loss to nutrient yield loss this represented reductions of 8.1 and 9.2 kg ha−1 in nitrogen and 1.5 and 1.6 kg ha−1 in phosphorus, respectively. Likewise, it was estimated that weed
