Problems solved by technology

Through a large number of indoor bioassays and field drug efficacy tests, the inventor found that the combined application of Spodoptera litura nucleopolyhedrosis virus and metaflumizone can not only reduce the dosage of pesticides, expand the insecticidal spectrum, increase the lethal speed of pests, and prolong the life of the pests. Insecticidal duration, delayed resistance, safe for the environment; and related compounding of Spodoptera litura nuclear polyhedrosis virus and metaflumizone has not been seen at home and abroad.

Embodiment 1

[0026] Preparation Example 1 Spodoptera litura nucleopolyhedrosis virus metaflumizone wettable powder

[0027] Spodoptera litura nuclear polyhedrosis virus 20 billion PIB / ml, metaflumizone 60%, p-methoxy fatty amidobenzenesulfonic acid (dispersant) 8%, silkworm excrement (wetting agent) 8%, diphenyl Add 0.3% ketone (ultraviolet protective agent) and diatomaceous earth to 100% to prepare 20 billion PIB / ml Spodoptera litura nuclear polyhedrosis virus • 60% metaflumizone wettable powder.

Embodiment 2

[0028] Preparation Example 2 Spodoptera litura nuclear polyhedrosis virus metaflumizone wettable powder

[0029] Spodoptera litura nuclear polyhedrosis virus 10 billion PIB / ml, metaflumizone 40%, alkylamino taurate (dispersant) 6%, pull-off powder X (wetting agent) 6%, tryptamine Acid (ultraviolet protective agent) 0.2%, kaolin added to 100%, prepared 10 billion PIB / ml Spodoptera litura nuclear polyhedrosis virus • 40% metaflumizone wettable powder.

Embodiment 3

[0030] Preparation Example 3 Spodoptera litura nucleopolyhedrosis virus metaflumizone wettable powder

[0031]Spodoptera litura nuclear polyhedrosis virus 5 billion PIB / ml, metaflumizone 20%, lignosulfonate (dispersant) 5%, sodium dodecylbenzenesulfonate (wetting agent) 4%, formazan Add 0.1% octyl oxycinnamate (ultraviolet protective agent) and white carbon black to 100% to prepare 5 billion PIB / ml Spodoptera litura nucleopolyhedrosis virus • 20% metaflumizone wettable powder.

[0032] The specific processing steps of the virus insecticide wettable powder are as follows: according to the above formula, the active ingredients Spodoptera litura nucleopolyhedrosis virus, metaflumizone, dispersant, wetting agent, ultraviolet protection agent, and filler are mixed, and mixed in a mixing tank Mix evenly, and then mix evenly after being pulverized by an airflow mill, and then the wettable powder of the present invention can be prepared.

Abstract

The invention relates to the field of pesticides, and discloses a viral pesticide which comprises the active components of a spodoptera litura nuclear polyhedrosis virus and metaflumizone. The content of inclusion bodies of the spodoptera litura nuclear polyhedrosis virus ranges from 0.1 billion PIB / ml to 50 billion PIB / ml, and the weight percentage of metaflumizone ranges from 0.1% to 80%. The viral pesticide can be prepared into wettable powder, water dispersible granules, suspending agents and emulsion in water. After the two active components are compounded, an obvious synergistic effect is achieved, the pesticide dosage can be reduced, the pesticidal spectrum can be enlarged, the pesticidal death speed is increased, the pesticidal duration time is prolonged, resistance is delayed, and the viral pesticide is safe to crops and environment.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a virus insecticide containing metaflumizone, which is used for preventing and controlling crop Lepidoptera pests. Background technique [0002] Spodoptera litura is a polyphagous pest. It is known that it can harm more than 290 kinds of plants in 99 families, among which more than 90 kinds of plants are preferred. [0003] As one of the important means of biological control, insect virus has the advantages of strong specificity, high virulence, good stability, safety and harmlessness. After use, it can cause the spread of viral diseases in pest groups, and can be naturally controlled for a long time Pests ebb and flow, causing successive generations of pests to continue to carry viruses and die from infection. Compared with other chemical pesticides and biological pesticides, insect virus insecticides have not found resistance problems so far, which brings a good opportunity f...
