At present, the phenomenon of waste by cotton farmers is also very serious, which not only aggravates the contradiction of the supply of pesticides , but also increases the input cost of cotton production in the key cotton-producing areas. It also brings environmental pollution, cotton buds and fruits to the countryside. The adverse effects of various aspects such as phytotoxicity.
Recently, a large survey of cotton farmers has been conducted for many years. There are five kinds of wastes in the use of cotton pesticides:
In one case, some cotton farmers use the equivalent of a pesticide bottle when diluting the pesticide. Based on the feeling, the pesticide is estimated to be inaccurate, so the pesticide is not accurate, 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.
In the second case, the large cotton planter mistakenly believes that the greater the concentration of pesticides used, the more favorable it is to control the pests and diseases of cotton bollworm, cotton bollworm, Spodoptera litura, cotton red spider, cotton aphid, blight and so on. Therefore, the concentration of pesticides is increased at will, and some are even two or three times higher than the normal use concentration.
In the third case, 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.
In the fourth case, some cotton farmers always like to mix pesticides that cannot be mixed, so that the active ingredients of the pesticides are directly destroyed. Not only is the pesticides artificially caused, but it is also easy to produce certain phytotoxicity to the cotton crops of high quality cotton varieties.
The fifth situation is that some cotton farmers do not use interlaced spray 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 shaker, do not carefully check whether the appliances are sprayed before spraying. Leakage, blockage, sprayer liquid medicine is too full, 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. China Pesticides Network Xiaobian provides the following data, only for cotton farmers' reference: 1000g of pesticide bottle cap, its volume is 13ml; 500g of pesticide bottle cap, its volume is about 12.5ml; 250g loaded pesticide bottle Cover the volume of 6 ml; 100 g of pesticide bottle cap, the volume is about 3.5 ml.
