Embodiment approach 1

[0009] Embodiment 1: The biological pesticide consists of 14g of fenvalerate technical, 2g of phenethylphenol polyoxyethylene ether, 2g of ethylene glycol, 3g of xylitol, 2g of polyvinyl alcohol, 0.3g of triethylamine, and 10g of biomass. production. The biomass is made by mixing Delphinium and Niuchao Veng at a weight ratio of 1:1, then pulverizing, adding 8 times the amount of 70% ethanol, soaking 3 times for 24 hours each time, filtering, combining the soaking solution, and recovering under reduced pressure. It is made without alcohol. Add the weighed fenvalerate, phenethyl phenol polyoxyethylene ether, ethylene glycol and xylitol into the reaction kettle, heat it to 60°C at a rate of 15°C / min to melt the original drug, and stir it evenly. Oil phase. The weighed polyvinyl alcohol, biomass, triethylamine and appropriate amount of water are mixed uniformly, and slowly heated to 70° C. to prepare a water phase. The oil phase is slowly injected into the water phase, and a hig...

Embodiment approach 2

[0010] Embodiment 2: The biological pesticide is composed of 16 g of fenvalerate technical, 3 g of phenethyl phenol polyoxyethylene ether, 3 g of ethylene glycol, 4 g of xylitol, 3 g of polyvinyl alcohol, 0.5 g of triethylamine, and 12 g of biomass. The preparation method is the same as the first embodiment.

Embodiment approach 3

[0011] Embodiment 3: The biological pesticide is composed of 18 g of fenvalerate original medicine, 4 g of phenethyl phenol polyoxyethylene ether, 4 g of ethylene glycol, 5 g of xylitol, 5 g of polyvinyl alcohol, 0.6 g of triethylamine, and 14 g of biomass. The preparation method is the same as the first embodiment.

Abstract

The invention discloses a biological medicament for preventing and treating ginger worms and a preparation method of the biological medicament, belonging to the technical field of biological pesticides. The biological medicament is prepared from active component fenvalerate, biomass and an aid. Indoor toxicity tests show that active component fenvalerate in the biological medicament can generate arelatively good synergistic effect after being compounded with the biomass; and meanwhile, field tests prove that the prevention and treatment effects of the biological medicament on the ginger wormsare obviously superior to a control group, and the side effect is low.

Description

Technical field [0001] The invention belongs to the technical field of biological pesticides, and particularly relates to a biological agent for preventing and treating ginger borer and a preparation method. Background technique [0002] When the applicant used the summer vacation time to do farm work, he found that the stems and leaves of ginger in the ground were withered and withered. After peeling off the stems and leaves, it was found that a kind of insect was damaging the ginger stems. After searching the information, it was confirmed that it was a ginger borer. The ginger borer (also known as the corn borer, belonging to the Lepidoptera, Oscaridae) is the main pest that harms ginger. It has a very mixed feeding habit. When it is harmful, larvae bite the tender stems, and then bore the stems (there are worm debris and insect dung accumulation at the boreholes), which hinders the transportation of water and nutrients, and makes the stems and leaves above the boreholes turn ...
