Problems solved by technology

[0005] At present, there are few pesticides registered for the control of edible fungus pests in my country. The control of Pleurotus ostreatus mainly uses organic phosphorus and pyrethroid chemical agents. Since there is no ideal biological pesticide, the pesticide residues of edible fungi exceed the standard Seriously, affecting its nutritional value and destroying the ecological environment

Embodiment 1

[0029] A biopesticide for preventing and controlling Pleurotus pleurotus, the weight percentage of raw materials is: 1% of buttercup extract, 0.5% of ivermectin, 8% of starch, 2% of dextrin, 2,6-di-tert-butyl-p-methyl 1% phenol, 1% benzophenone, 0.2% acetic acid, and the balance is bean cake.

[0030] The preparation method is as follows:

[0031] (1) Crush the whole ranunculus into 80-mesh powder, take 2 kg, add 12 kg of 60% ethanol solution, add 0.05% zinc chloride accounting for the weight of the powder, stir well, and ultrasonically treat at 50°C for 3 minutes, then Shake and extract at 60°C for 60 minutes, filter to obtain the filtrate;

[0032] (2) Pour 12 kg of 70% ethanol solution into the ranunculus filter residue, add 2% polyethylene glycol accounting for the weight of the powder, stir well, shake and extract at 50°C for 40 minutes, filter to obtain the filtrate;

[0033] (3) Combine the above two filtrates, suck it into a vacuum decompression concentration tank, a...

Embodiment 2

[0036] A biopesticide for preventing and controlling Pleurotus pleurotus, the weight percentage of raw materials is: 1.5% of buttercup extract, 0.5% of ivermectin, 9% of starch, 6% of dextrin, 2,6-di-tert-butyl-p-methyl 2% phenol, 1% benzophenone, 0.3% acetic acid, and the balance is soybean cake.

[0037] The preparation method is the same as in Example 1.

Embodiment 3

[0039] A biopesticide for preventing and controlling Pleurotus pleurotus, the weight percentage of raw materials is: 2% of ranunculus crude extract, 0.2% of ivermectin, 8% of starch, 2% of dextrin, 2,6-di-tert-butyl p- 2.5% cresol, 2.5% benzophenone, 0.2% acetic acid, and the balance is soybean cake.

[0040] The preparation method is the same as in Example 1.

Abstract

The invention belongs to the technical field of biopesticide and particularly relates to biopesticide for preventing and treating lycoriella pleuroti Yang et Zhang and a preparing method thereof. The biopesticide is prepared from, by weight, 1-10% of Japanese buttercup herbs, 0.01-5% of ivermectin, 5-40% of a binding agent, 0.1-5% of a stabilizing agent, 0.01-0.5% of a pH value modifier and the balance bean cake. The compounded biopesticide of plant sources is good in effect of preventing and treating lycoriella pleuroti Yang et Zhang, long in lasting period, efficient, low in toxicity and residue and environmentally friendly, and does not generate drug resistance; the biopesticide has a function of fertilizer while preventing and treating lycoriella pleuroti Yang et Zhang, and improves a pleurotus ostreatus culture medium, and the raw materials are easy to obtain.

Description

technical field [0001] The invention belongs to the technical field of biopesticides, and in particular relates to a biopesticide for controlling Pleurotus ostreatus and a preparation method thereof. Background technique [0002] Lycoriella pleuroti Yanget Zhang (Lycoriella pleuroti Yanget Zhang), commonly known as fungus mosquitoes and maggots, is the dominant species of Pleurotus pleuroti Yanget Zhang, and is the main pest that harms edible fungi. The worm is widely distributed in various regions of my country, causing damage to mushrooms, fungus, ganoderma and other edible and medicinal fungi. Pleurotus pleurotus mainly sneaks into the compost and fruiting bodies with larvae, and directly eats the mycelia of edible fungi and the primordia of the compost or bores young young mushroom bodies, causing the fungus to retreat, the primordia to disappear, and the compost to loosen and Gradually turn yellowish brown, the mushroom buds shrivel and die, the stipe is broken and lod...
