The rainy season is a high incidence of crop pests and diseases, but it is difficult to exert a greater effect if the pesticide is not paid attention to during the rainy season. In order to ensure the maximum effect of the drug, the following five points are expected:
First, pay attention to the weather and apply the medicine at the right time. It is best to rain after applying the medicine or raining while applying the medicine. It should be selected during the weather period and the application time should be selected according to the activity rules of the pests.
The second is to choose the right agent. In the rainy season, it is best to use systemic, quick-acting, rain-tolerant and microbial pesticides.
The third is to add an adhesive and an auxiliary synergist to the liquid. Adding adhesion substances such as washing powder, tapioca water and tea leaching solution to pesticides can enhance the adhesion of pesticides on crops and pests, and improve the control effect. Note that washing powder and tea leaching solution should not be compatible with acidic pesticides. Mixed.
The fourth is to increase the concentration of pesticides (except for highly toxic pesticides), and the effect of disease prevention, pest control and weeding is better.
The fifth is to improve the method of application. If a systemic insecticide is selected, the soil will be applied to the roots of the crops before the large-scale occurrence of the pests, so that the plants can be absorbed and the pests can be poisoned and died.
PET Woven Geotextile is high strength woven geotextiles manufactured by weaving high tenacity polyester filament yarns into a dimensionally stable network. The inherent characteristics of polyester – high tensile strength and modulus, low elongation, low creep and high long-term design strength - makes these products ideal for soil reinforcement applications. The fabric develops excellent frictional interaction with a wide variety of soils and granular materials.
The relatively small openings of these fabrics enable them to act as efficient separators preventing the mixing of costly granular materials with fine-grained soils. The geotextile has reasonably high permeability to prevent excessive build-up of pore-pressures due to applied loadings.
