The author has been engaged in agro-technical extension work in Huaihai Farm in Jiangsu Province for nearly 30 years. He is well aware of the role of rational use of pesticides in the increase of grain production. The field is also a national high-quality commodity grain production base, and the prevention and treatment of pests in 80,000 mu of paddy rice. China has paid great attention to environmentally-friendly low-carbon drugs, which has fundamentally solved the problem of food security and received good social effects. Now the author has listed their methods of using pesticides for your reference.
Uniform purchase of medicines: Farm purchases of bulk pesticides are made through the annual and current formulation of pesticides used by the Agricultural Technology Division of the Farm and purchased by the Farm Unified Organization. To qualified, reputable, and powerful pesticide distributors, the large-scale purchases on the one hand greatly reduce the cost of agricultural resources, and at the same time ensure the quality of the pesticides, and the characteristics of high efficiency, low toxicity, and low residue, so as not to Pesticides that meet food safety requirements are kept out of farm gates.
Survey and selection of drugs: The farm established a pest monitoring station, established a three-tier plant protection protection patrol network, and established a pest intelligence sharing mechanism with neighboring farm villages to identify the specific time and amount of occurrence of each batch of rice pests and diseases. And the degree of damage, and then through the analysis to determine whether the use of drugs, the types and concentration of a variety of liquid medicine, and through the establishment of farm units in the agricultural machinery plant protection team quickly deploy control to complete the extinguishment, to achieve the purpose of unified defense.
Tolerance to drug use: For each pest occurring in paddy fields, the time, number, distribution, natural enemies, and extent of damage are analyzed. If the control cost is not comparable to or higher than the yield loss caused by pest control, Give up medication, reduce the number of medications in the field, and reduce the cost of medication and food production.
Cultivation-limiting drugs: It is through the promotion of rice varieties resistant to pests (resistance) and pests, adjustment of fertilizer types, application rhythms, and various physics, mechanical, and biological measures of rice in various stages of fertilization, especially in the early stages of rice planting. Through the promotion and cultivation of resistant (resistant) pest rice varieties, the tendent pests are induced to be destroyed or cultivated through tolerance, and the number of pests in other plots is reduced, thereby achieving the purpose of cost-saving drug use and effective disease prevention and pest management.
Insecticide-free application: Through many years of cultivation practices, the majority of scientific and technical personnel of the farm have entered the concept of low-carbon pesticides in the management cadres and the workforce in order to import pests, insects, drugs, and pest control. The sensitive period before serious damage or when young pests are not resistant to insecticides and weak in resistance to pesticides is eradicated, that is, when ordinary people do not see the tiny or spotty state of the pests in the naked eye, they use very few The amount of drug to achieve effective protection.
Interval avoidance: Before entering the peak season of rice bloom in September or later period, the farm will take administrative measures to investigate and treat pests, and then use long-term, low-toxic pesticides to maintain efficacy. Afterwards, it was banned by the ban on the reapplication of pesticides in rice fields so that the low-toxicity, low-residue pesticides that had accumulated and adhered to the rice leaf, plant body or rice would have sufficient time to attenuate and prolong the use of pesticides before rice was harvested. The intervals allow the food to truly achieve green safety quality.
