Embodiment 1

[0023] 100 billion PIB / g Spodoptera litura NPV-sz-1 former powder 100g is mixed with 65% emamectin benzoate (amamectin benzoate) former powder 100g, adds sterile water 5kg, uses Mix thoroughly with a mixer. Then add 200 g of sodium dodecylbenzene sulfonate as a dispersant, 300 g of diethylene glycol as a stabilizer, and 40 g of a fluorescent whitening agent as a photoprotectant, and fully mix with a stirrer. Dilute the volume to 10000mL with sterile water, fully mix with a stirrer, and obtain 1% emamectin benzoate-spodoptera NPV-sz-1 insecticidal suspension concentrate with a content of 1 billion PIB / mL after sub-packaging.

[0024] The dispersant can also be one of lignosulfonate, sodium lauryl sulfate, fatty alcohol ethoxylate, alkylphenol ethoxylate, sodium octadecyl sulfosuccinate, polycarboxylate species or a mixture of several species. The stabilizer can also use one or a mixture of ethylene glycol, propylene glycol, glycerol, triethylene glycol, polyethylene glycol, s...

Abstract

The invention discloses a composite biological insecticide and a preparation method thereof, which belongs to the technical field of biological pesticide. The state prodenia litura nuclear polyhedrosis virus Suzhou No.1 (SpltNPV-sz-1) is stored in China Typical Culture Conservation Center on June 25, 2008 with the collection number of CCTCC No: V200806. The composite biological insecticide comprises the following components in weight: 1 to 10 percent of prodenia litura NPV-sz-1 raw powder, 0.1 to 3 percent of methylamino abamectin benzoate raw powder, and the balance being functional addition agents and solvent. The composite biological insecticide and the preparation method thereof have the characteristics of high efficiency, broad spectrum and no pollution; the composite biological insecticide is suitable for preventing and controlling lepidopterous pests and mites such as the prodenia litura, diamondback moth and diaphania indica, widens the desinsection range, improves the desinsectio effect, delays the generation of insecticides resistance of insects, plays the continuous natural control role, reduces the usage amount of chemical pesticide, lowers the cost, protects the entironment and has wide application prospect.

Description

technical field [0001] The invention belongs to biological pesticides for preventing and controlling agricultural pests, and relates to a high-efficiency, broad-spectrum, and pollution-free biological insecticide compounded by Spodoptera litura nuclear polyhedrosis virus and emamectin benzoate as effective active ingredients It is used to control Lepidoptera pests and mites such as Spodoptera litura, Diamondback Moth, Melon Borer, Beet Spodoptera, and Cotton Bollworm. Background technique [0002] With the continuous development of the national economy and the improvement of people's living standards, people have higher and higher requirements for the quality of various agricultural products, especially the safety of products has been widely concerned and valued. At present, in the prevention and control of various crop diseases and insect pests, the situation of excessive reliance on chemical pesticides is still very serious, which has brought about problems such as pest re...
