Example Embodiment

[0047]Example 1: In order to understand the control effect of indoxacarb·trifluoropyrimidine bucket mix on rice brown planthopper, a field experiment was carried out in the experimental demonstration area of ​​Haohuahong Town, Huishui County in June 2019, and the experiment was used in the rice heading to grain filling period Indoxacarb and trifluorophenyl pyrimidine commercial drugs in the laboratory were subjected to tank-mix spray test

[0048]The experiment set 15% indoxacarb suspension (active ingredient dosage 67.5g a.i. / hm2), 10% trifluorophenyl pyrimidine suspension (active ingredient dosage 37.5g a.i. / hm2), indoxacarb·trifluorophenyl pyrimidine combination (active ingredient dosage 48.75ga.i. / hm2), clean water control, a total of 4 treatments, each treatment is repeated 3 times, a total of 12 plots, each plot is randomly arranged, the plot area is 30m2, Used 3WBJ-16DZ multifunctional electrostatic sprayer to spray on August 20. Before spraying and 3, 7, and 14 days after spray...

Abstract

The invention discloses a high-efficiency novel synergistic composition for preventing and treating brown planthopper of rice. The high-efficiency novel synergistic composition comprises a main effective component consisting of indoxacarb and trifluoro-benzene pyrimidine. The mass ratio of indoxacarb to trifluoro-benzene pyrimidine in the main effective components is 5: 1. Compared with the priorart, the indoxacarb and the trifluoro-benzene pyrimidine are combined and mixed for use, the composition has an obvious synergistic effect on prevention and treatment of the brown planthopper of the rice, the field prevention and treatment effect reaches up to 93.04%, the prevention and treatment effect is remarkable, the use amount of pesticides can be effectively reduced, various diseases can betreated, drug resistance of pests is delayed, and the production cost is reduced. The method is simple and easy to implement, wide in material source, low in cost and good in using effect.

Description

technical field [0001] The invention relates to the technical field of agricultural science and technology, in particular to a novel synergistic combination with high efficiency for controlling rice brown planthopper. Background technique [0002] Brown planthopper Nilaparvata lugens It is an important pest in rice production. It has the characteristics of monophagia, migration, and destructiveness, and it is very easy to break out and cause disasters. The "honeydew" excreted can also promote the growth of germs, and its stylet can also be used as a vector for plant viruses. This has led to a serious decline in rice yields, and even grain failure in rice fields, resulting in huge economic losses. In the comprehensive management of N. lugens, chemical control plays a vital role in the comprehensive control due to its advantages of speed, efficiency and economy. However, with the application of a single large dose of chemical agents, the problem of resistance becomes more a...
