Embodiment 1

[0029] Spodoptera litura nuclear polyhedrosis virus: 1 billion PIB / mL

[0030] Tebufenozide: 10%

[0031] Calcium lignosulfonate: 4%

[0032] Ethylene glycol: 3%

[0033] Isooctanol: 1%

[0034] Activated silica: 2%

[0035] Fluorescent whitening agent: 0.3%

[0036] pH regulator: 0.5%

[0037] The balance is water.

Embodiment 2

[0039] Spodoptera litura nuclear polyhedrosis virus: 1 billion PIB / mL

[0040] Tebufenozide: 12%

[0041] Calcium lignosulfonate: 3%

[0042] Ethylene glycol: 2%

[0043] Isooctanol: 1%

[0044] Activated silica: 2%

[0045] Fluorescent whitening agent: 0.5%

[0046] pH regulator: 0.3%

[0047] The balance is water.

[0048] Biological Example 1:

[0049] The indoor toxicity of Spodoptera litura nucleopolyhedrosis virus, tebufenozide and the agents of the examples to Spodoptera litura was measured respectively by leaf dipping method, and Abbott formula was used to correct the mortality rate of each treatment. For the convenience of calculation, 1×10 8 PIB / g Spodoptera litura nucleopolyhedrosis virus is as the former medicine, and content is 100%, and the content of active ingredient in the embodiment medicament is expressed as mg / L, calculates virulence regression equation and LC 50 and LT 50 . Then with reference to the method of Mansour, 25% (LC 25 ) doses are mix...

Abstract

The invention relates to a pesticide suspending agent, which is characterized in that the pesticide suspending agent is prepared from the following raw materials in proportion by weight: 0.5 to 2 billion PIB of Spodoptera litura nucleopolyhedrovirus per milliliter, 3 to 15 percent of tebufenozide, 1 to 5 percent of wetting dispersant, 0 to 5 percent of emulsifier, 1 to 10 percent of solvent or cosolvent, 1 to 5 percent of filler or carrier, 0 to 0.8 percent of fluorescent whitening agent, 0.1 to 1 percent of pH regulator, and the balance being water.

Description

technical field [0001] The invention relates to a pesticide suspension, in particular to a pesticide suspension containing Spodoptera litura nucleopolyhedrosis virus and tebufenozide. Background technique [0002] Spodoptera litura is an omnivorous pest of Lepidoptera Noctuidae. It has a wide distribution range and mainly harms crops such as Brassicaceae, Solanaceae, Cucurbitaceae, and Legumes. Spodoptera litura is distributed all over my country. It has 4-5 generations in North China, 5-6 generations in the Yangtze River Basin, and 6-9 generations in Fujian. It can reproduce all year round in Guangdong, Guangxi, Fujian, and Taiwan without overwintering. In recent years, with the change of farming practices, the occurrence and damage of Spodoptera litura is increasing year by year. So far, the control of Spodoptera litura mainly relies on chemical agents, but due to the frequent use of chemical agents, Spodoptera litura has developed resistance to many agents. In addition,...
