Embodiment 1

[0029] Beet armyworm nuclear polyhedrosis virus: 2 billion PIB / mL

[0030] Tebufenozide: 3%

[0031] Sodium Lauryl Sulfate: 2%

[0032] Farm Milk 500#: 2%

[0033] Propylene Glycol: 2%

[0034] Isooctanol: 1%

[0035] Activated silica: 2%

[0036] Fluorescent whitening agent: 0.3%

[0037] pH regulator: 0.5%

[0038] The balance is water.

Embodiment 2

[0040] Beet armyworm nuclear polyhedrosis virus: 1 billion PIB / mL

[0041] Tebufenozide: 5%

[0042] Sodium Lauryl Sulfate: 2.5%

[0043] Agricultural Milk 500#: 1.5%

[0044] Propylene Glycol: 2%

[0045] Isooctanol: 1%

[0046] Activated silica: 2%

[0047] Fluorescent whitening agent: 0.5%

[0048] pH regulator: 0.3%

[0049] The balance is water.

[0050] Biological Example 1:

[0051] The indoor toxicity of beet armyworm nuclear polyhedrosis virus, tebufenozide and the agents of the examples to beet armyworm were respectively measured by the leaf soaking method, and the mortality rate of each treatment was corrected by Abbott formula. For the convenience of calculation, 1×10 9 PIB / g beet armyworm 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,...

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 exigua nucleopolyhedrovirus per milliliter, 3 to 10 percent of tebufenozide, 1 to 4 percent of wetting dispersant, 1 to 3 percent of emulsifier, 1 to 5 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 beet armyworm nuclear polyhedrosis virus and tebufenozide. Background technique [0002] Beet armyworm is an important agricultural pest in my country. It mainly harms nearly a hundred kinds of crops such as vegetables and soybeans, and causes great economic losses to vegetable farmers and farmers. In the past, beet armyworm only occurred in southern my country, and its damage was limited to vegetable fields, and occurred intermittently. In recent years, with the impact of global warming and other factors, the occurrence and damage of beet armyworm has been increasing year by year. At present, beet armyworm has not only become the main pest on vegetables in our country, but also has serious outbreaks on soybeans, cotton and other crops. Due to the fast reproduction speed and many generations of beet armyworm, and the control of beet armyworm for many y...
