In recent years, with the increasing use of pesticides and the increase in the number of pesticides, the problem of pest resistance has become more and more prominent. This has not only brought about a serious loss of crops and a significant loss of farmers' economic benefits, but also the quality and safety of agricultural products and the safety of ecological environment. Brings immeasurable impact. The problem of resistance is far more serious than people think. Shen Jinliang, a professor at Nanjing Agricultural University, has long been concerned about and researched the problem of pest resistance. He revealed that the current stem borer is one of the main pests in rice fields. Since 2008, bis-amide chlorantraniliprole and flubendiamide have been The high-efficiency agent of Chilo suppressalis, but with the increase of the dose and the increase of the number of medications, the resistance begins to appear after 4~5 years, especially in southern and central Zhejiang, around Poyang Lake in Jiangxi, Hengyang, Hunan. In the rice areas of other places, the effect of bisamides such as chlorantraniliprole on the control of Chilo suppressalis has been greatly reduced, and the list of control agents has basically been withdrawn. The problem of resistance to rice stem borer is far more serious than people think. Shen Jinliang emphasized that not only bisamide products, but also some agents that have been excellent in controlling pests such as chlorfenapyr, avermectin, and acesulfame, because of the high dose, the resistance is also rising; even some areas are banned in rice. The use of fipronil and the highly toxic chlorpyrifos, which has been banned, are also used. Professor Shen analyzed that although this has a lot to do with the repeated use of pesticides by farmers, it is traced back to the non-standard production of some pesticide companies and dealers selling drugs at will. At present, some pesticide companies and distributors guide farmers to use and abuse pesticides for the immediate benefit. If this situation cannot be effectively curbed, rice pests in the future may enter an era when medicine is not available, and the large-scale use of pharmaceuticals also makes agricultural products quality and safety. Unable to guarantee, pesticide reduction is also difficult to implement. The company plays a vital role Chen Biao, Marketing Director of Jiangsu Baoling Chemical Co., Ltd. pointed out that the current low level of drug use and the aging of the planting population are very serious. Most farmers think that it is a good medicine to kill the insects before they are used, and the dealers want to cater to them. Farmers' psychology, some good medicines allow farmers to use them repeatedly, resulting in resistance. In some areas, the phenomenon of adding hidden components to pesticide companies is more serious, and even mixed cases of multiple ingredients are present. Farmers feel good in use and fast in use, but they increase the risk of pest resistance in the subtle way, making it difficult to prevent and control in later stages. Adding difficulty, vicious circle, and adding hidden components at will also easily cause phytotoxicity. Shen Jinliang believes that in order to extend the service life of a single compound, companies play a vital role. Enterprises must have a sense of social responsibility and guide farmers to alternate medicines. In addition, China's pesticide companies generally have insufficient innovation ability, or they must change the status quo of pesticide use from improving their own competitiveness, so as to achieve product development and quality management. In particular, in terms of pesticides , some of the compound products in the past proved to be very effective in field control. Therefore, the pesticide management department should encourage enterprises to focus on the research and development of complex products that are effective or efficient, but should strictly control the chaos of pesticide compound products in China, and ensure that farmers have ideal and can be used to delay and control pest resistance. The selected pesticide is available. Try some old varieties. Amides are the key products in current insecticides. If resistance problems arise, many commonly used drugs will fail now. How to delay their resistance is a problem that needs to be paid attention to at present. Yu Hongbing, general manager of Jiangsu Tonglian Agricultural Resources Chain Co., Ltd. said that after several years of exploration and summarization, it was found that some old varieties have good effects, such as the effect of buprofone compounding, and other herbicides such as quinclorac. Re-use on rice again, the use of wheat herbicide Isoproturon, insecticidal + amide is also very effective. This also reflects the fact that the increase in resistance has prompted some old pesticides that have not been used for a long time and eliminated by the market to regain favor, but the old pesticides generally have problems such as complicated drugs and low safety. "The development of pesticides can't go back to the old and complicated roads of fighting drugs. How to delay the resistance of products, or need to do a good job of unified defense, plant protection stations must be strictly controlled." Yu Hongbing said that the current farmers only consider drugs The current effect, regardless of long-term development, has made some low-cost, non-standard pesticides highly sought after. For example, some areas use Avi-Fluorose to control rice leaf roller, which is actually uncontrollable. It must be added with hidden components such as chlorantraniliprole and fipronil. With the promulgation of the new "Regulations", it is believed that some enterprises will be restrained by the arbitrarily adding hidden elements, and the phenomenon of pesticide abuse and misuse will also be reduced. Shen Jinliang also said that it is far from enough to improve the level of drug use by enterprises, and it also needs the state's macroeconomic regulation and control. It is necessary to strengthen the construction of the unified defense and control, and according to the prediction of the plant protection station, the farmers should be given good medicines early, and the status quo of low-level drug use by farmers can be compensated through farmers' training and paper understanding. In addition, many experts suggest that while focusing on chemical control, it is necessary to carry out green prevention and control in a timely manner, and comprehensive use of biological control methods such as insect natural enemies, sexual attractants, and insecticidal lamps is an effective means to suppress the rise of drug resistance.
