Aerial plant protection preparation for controlling diseases and pests in rice fields

Abstract

The invention provides an aerial plant protection preparation for controlling diseases and pests in rice fields, and belongs to the field of pesticide compositions. The aerial plant protection preparation comprises the following components in percent by weight: 2-10% of thifluzamide, 5-15% of trifloxystrobin, 1-7% of nitenpyram, 1-5% of chlorantraniliprole, 2-7% of a dispersant, 1-5% of a wettingagent, 0.1-5% of a thickener, 2-6% of an antifreezing agent, 0.1-0.6% of a defoaming agent, 0.1-0.5% of a viscosity modifier, 1-5% of a stabilizer and the balance of water. After compounding of thifluzamide, trifloxystrobin, nitenpyram and chlorantraniliprole, the aerial plant protection preparation has an obvious synergistic effect and can simultaneously control various diseases and pests in thelater stage of rice growth; the aerial plant protection preparation is stable in performance, can be applied to aerial plant protection under a low-dilution ratio or undiluted condition, does not block nozzles, can quickly spread droplets on the surface of rice in a wet spreading manner, can simultaneously control various diseases and pests in the rice fields in the later stage of the rice growth,and has an ideal control effect.

Description

Technical field [0001] The invention belongs to the field of pesticide compositions, and specifically relates to an aerial control preparation used for the prevention and control of diseases and insect pests in rice fields. Background technique [0002] Rice is my country's most important food crop. At present, about 60% of the country's population mainly depends on rice. Rice production has ranked first among my country's three major food crops (rice, wheat, and corn) for many years. With the transfer of land, large-scale rice cultivation has become a trend. In the rice production process, the planting and harvesting links have been basically mechanized. However, in the rice management link, especially pest control, we still mainly rely on traditional manpower methods such as backpack sprayers and motorized sprayers, which do not meet the needs of modern industrial development. Aviation plant protection emerged to adapt to the times and play an important role in modern uni...

Problems solved by technology

[0006] When mixing agents with a synergistic effect, the effect cannot be conventionally expected. For example, the compound use of difenoconazole and fludioxonil has a synergistic effect, and the existing pesticide preparation of difenoconazole fludioxonil is sold and there is also a patent (publication number CN103553763A) that adopts chlorpyrifos (trade name Lesben) and fludioxonil to compound the pesticide composition, but Chen Hongyu etc. use phenyl ether fludioxonil and Lesben in combination to treat Astragalus root rot. It was found that the control effect of the compounded three pesticides was only 40.21%, while the compounded effect of difenoconazole and Lesben (chlorpyrifos) was 44.13% (Chen Hongyu, Mao Zhengyun. Several pesticides compounded Field efficacy test of formula for controlling Astragalus root rot[J].Agricultural Science and Information, 2014(2):33-34)

At present, the four pesticides of thifuramide, trifloxystrobin, nitenpyram and chlorantraniliprole are all registered for use in rice. There is a patent report on the synergistic effect of benzamide combination on rice diseases and insect pests, but there is no report on the quaternary mixing of the above-mentioned medicaments and preparation of an aerial control preparation suitable for rice breaching stage
