Pesticide suspending agent containing Spodoptera litura nucleopolyhedrosis virus and emamectin benzoate-chlorfenapyr

A nuclear polyhedrosis virus, Spodoptera litura technology, applied in the directions of insecticides, biocides, animal repellents, etc., can solve the problem of no Spodoptera litura nucleopolyhedrosis virus and emamectin mixed, no Spodoptera litura. The problem of mixing nuclear polyhedrosis virus and emamectin into a suspension agent, etc., can improve the level of biological control, reduce the toxic effect, and reduce the dosage.

Embodiment 1

[0029] Spodoptera litura nuclear polyhedrosis virus: 2 billion PIB / mL

[0030] Emamectin benzoate: 0.5%

[0031] Farm Milk 602#: 4%

[0032] Farm Milk 500#: 2%

[0033] Ethylene glycol: 3%

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

[0041] Emamectin benzoate: 1%

[0042] Agricultural Milk 602#: 4.5%

[0043] Agricultural Milk 500#: 1.5%

[0044] Ethylene glycol: 2%

[0045] Isooctanol: 1%

[0046] Activated silica: 2%

[0047] Fluorescent whitening agent: 0.5%

[0048] pH regulator: 0.5%

[0049] The balance is water.

[0050] Biological Example 1:

[0051] Leaf dipping method was used to measure the indoor toxicity of Spodoptera litura nuclear polyhedrosis virus, emamectin emamectin and the medicaments of the examples to Spodoptera litura respectively, and the Abbott formula was used to correct the mortality rate of each treatment. For the convenience of calculation, 1×10 9 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 ...

Description

technical field [0001] The invention relates to a pesticide suspension, in particular to a pesticide suspension containing Spodoptera litura nucleopolyhedrosis virus and emamectin benzoate. 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 add...
