Pesticide waste is a common phenomenon in rural areas. At present, it is a critical period for cotton medicine. Many cotton farmers use drugs for good harvests, resulting in waste of pesticides. They not only have no effect on cotton, but also seriously pollute the environment. The pesticides are briefly summarized. The pesticide waste is mainly manifested in the following five situations: First, some cotton farmers in the dilution of pesticides, the pesticide bottle caps equivalent, based on the feeling of estimating the drug, so the pesticide is very inaccurate, not too much or too little. Too much phytotoxicity caused by cotton, rice and other crops will cause excessive pesticide residues, affecting the quality of agricultural products. If the dosage is too small, it will not work and will not reach the effect of treating insects. Second, large cotton-growing households mistakenly believe that the greater the concentration of pesticides used, the more beneficial it is to controlling cottonworms, cotton bollworms, Spodoptera litura, cotton spider mites, cotton aphids, blight and other diseases and insect pests in the middle and late stages of cotton. Therefore, the concentration of pesticides is increased at will, and some are even two or three times higher than the normal use concentration. Third, some cotton farmers do not understand the relationship between pests and diseases and pesticides. When using pesticides, they are blind and have often caused the wrong use of drugs. It is difficult to achieve effective prevention and control of pests and diseases. Fourth, some cotton farmers always like to mix pesticides that cannot be mixed, so that the active ingredients of pesticides are directly destroyed. Not only does it cause artificial waste of pesticides, but it is also easy to produce certain phytotoxicity to cotton crops of high quality cotton varieties. Fifth, some cotton farmers do not use interlacing sprays when using manual sprayers. Instead, they use drugs in cotton fields at high temperatures and high temperatures at noon. When some farmers use the workers’ 16 hand-cranked sprayers, they do not carefully check whether the appliances leak before spraying. Blockage, the sprayer liquid is overfilled with the potion, and the medicine is wasted when the medicine is used. The waste phenomenon in the use of the above five pesticides cannot but cause the attention of the majority of farmers in key cotton-producing areas. Cotton plant protection technicians should also carry out propaganda in this area and strengthen technical guidance on cotton farmers' disease prevention and pest control, improve the level of cotton farmers' scientific drug use, promote scientific dilution of drugs, save money, prevent waste, and ensure drug efficacy. The following data is obtained from the small series of data, which is only for cotton farmers' reference: 1000 g of pesticide bottle caps with a volume of 13 ml; 500 g of pesticide bottle caps with a volume of about 12.5 ml; 250 g of pesticides The cap has a volume of 6 ml; the 100 g bottle of pesticide cap has a volume of about 3.5 ml. At present, it is the frequent occurrence of pests and diseases of crops such as cotton in the south. The author suggests that the relevant agriculture-related departments should present a one-time simple measuring tool when introducing pesticide dosage and redemption. Briefly introduce the method of use and provide a written information to facilitate the majority of cotton science. Formulated pesticides.
