The efficient use of pesticides is urgently needed to be upgraded

[China Agricultural Machinery Industry News] Agricultural mechanization is the foundation of agricultural modernization, a key factor in improving the comprehensive benefits of agriculture and improving the international competitiveness of agricultural products. It is an important way to deal with the transfer of rural labor and solve the problem of who will plant land. Recently, the National Agricultural Technology Extension Service Center held a national new plant protection machinery viewing demonstration and technical training activities in Shanghe County, Jinan City, Shandong Province. The aim is to speed up the promotion and application of new plant protection machinery, promote the upgrading of plant protection machinery in China, and improve the level of specialized equipment for pest control and pest control and the utilization rate of pesticides.
The use of pesticides is urgently needed to be upgraded

According to reports, this training event has invited the responsible persons and technical backbones of the plant protection technology promotion system from 29 provinces (autonomous regions and municipalities), the heads of more than 60 specialized pest control organizations, and 18 domestic and international production plant protection. More than 160 representatives of machinery companies participated in the training.
Plant protection machinery helps pesticides to be safely applied
“Renewal of plant protection machinery and upgrading of equipment level is an inevitable choice for realizing modern plant protection. By improving the technical content and equipment level of the application machine, it can not only improve the application level and pesticide utilization rate, but also improve the prevention and control effect and prevention. Control ability.” Wang Fengle, Director of the Department of Pesticide and Pharmaceuticals, National Agricultural Technology Extension Service Center, introduced 9 high-gap self-propelled boom sprayers and 16 different types of different types of unmanned aerial vehicles. The sprayer and five air-driven fruit sprayers were trained and the performance and technical parameters of each model were trained. “Through observation and training activities, plant protection systems and specialized prevention organizations will understand the new development status of existing practical plant protection machinery, master the performance parameters of different models, accelerate the promotion and application of new plant protection machinery, and comprehensively enhance major pest control. "Control ability and professionalism to control the level of equipment, have a positive role in promoting." Wang Fengle said.
The core of plant protection is the application of pesticides. Experts attending the meeting introduced that although China's pesticide production technology is at the advanced level in the world, because China's plant protection machinery still stays in the backward level of developed countries in the 1950s, there are about 58 million hand-held manual (electric) sprayers, accounting for the social preservation of plant protection machinery. The amount is 93.5%. The plant protection machinery can greatly improve the utilization rate of pesticides by improving the technical performance of the atomization effect, droplet size, penetration performance and distribution uniformity. According to estimates, the self-propelled sprayer sprayer has a pesticide utilization rate of about 50%, which is higher than 15% for liquid pump sprayers, 20%-40% for manual sprayers, and 30%-50% for backpack-type mobile fog machines. Its operating efficiency is 85 times that of manual sprayers and 15 times that of motorized sprayers.
Plant protection machinery is the key to achieving zero growth in pesticides
Relevant data show that there are about 120 kinds of agricultural agricultural pests and diseases in China, including 14 kinds of pests and diseases and about 100 kinds of second classes. The annual occurrence area is 7 billion mu, which is a huge hazard. In recent years, the state has vigorously promoted plant protection activities such as pest and disease monitoring, one spray, three defenses, and unified defense. The area of ​​prevention and control has reached 8 billion mu, and the annual recoverable losses account for about 17% of China's total grain output. Therefore, the zero-growth action of pesticide use proposed by the Ministry of Agriculture is to replace the low-efficiency small-scale plant protection machinery with large and medium-sized plant protection machinery through the technical means of “control, replacement, precision and integration”, thereby improving the utilization rate of pesticides, improving the efficiency of plant protection operations, and promoting The promotion of unified prevention and control has changed the chaotic situation of one household to spread drugs and improve the ability of prevention and control of pests and diseases.
“The improvement of plant protection machinery and equipment level is an important means to realize modern plant protection. The new plant protection machinery and equipment is the fundamental way to achieve zero growth in pesticide use. The lag of plant protection machinery is an important factor that restricts the development of pest control.” In the training session, Zhong Tianrun, deputy director of the National Agricultural Technology Extension Service Center, proposed and stressed that it is necessary to deepen the understanding of the importance of improving and improving the level of plant protection materials and equipment in China, and promote the use of pesticides in accordance with the Ministry of Agriculture to promote the specialization of major pests and diseases and the cooperation of agricultural enterprises. With regard to the deployment of zero-quantity growth, it is necessary to further strengthen the demonstration and demonstration of new plant protection machinery, comprehensively carry out the pesticide utilization test work, and carry out the implementation plan of the zero-growth action of pesticides by 2020 in accordance with the “Agricultural Enterprise Co-construction Demonstration Base” of the Ministry of Agriculture. 〉》Requirement, the plant protection system should do a good job of docking for pesticide companies, plant protection machinery enterprises and specialized prevention and control organizations, and cooperate for mutual cooperation. It is hoped that plant protection machinery enterprises and specialized prevention organizations will actively participate in the construction of demonstration bases for the reduction of pesticides. Provide support with security, for the good autumn grain crop pests and diseases prevention and control of major, win the annual agricultural harvest yield to contribute.
