Embodiment 1

[0025] According to 4.5% beta-cypermethrin emulsifiable concentrate and 0.05% biogas slurry by weight, biogas slurry compound beta-cypermethrin insecticide is prepared, mixed evenly, put into a sprayer, and sprayed. Catch the twenty-eight star ladybird adults in the field and feed them uniformly with kidney bean leaves. Select fresh non-toxic and insect-free kidney bean leaves, spray the front and back of the leaves (wet but not dripping), put them in disposable paper cups, and put 1 piece in each paper cup. Put into 20 adult beetles of twenty-eight star ladybugs in each paper cup then, seal with gauze and rubber band, prevention and control escape. Each treatment was repeated 3 times, and the number of live worms was investigated after 1 day, 2 days, and 3 days, and the mortality rate was calculated.

[0026] The above-mentioned methods of treatment are clear water (I), biogas slurry (II), 4.5% beta-cypermethrin 2000 times solution (0.05% by weight) (III) (the recommended do...

Embodiment 2

[0030] According to 70% imidacloprid water dispersant and 0.004% by weight of biogas slurry, biogas slurry compound imidacloprid insecticidal solution is prepared, mixed evenly, put into a sprayer, and sprayed.

[0031] Catch the twenty-eight star ladybird adults in the field and feed them uniformly with kidney bean leaves. Select fresh non-toxic and insect-free kidney bean leaves, spray the front and back of the leaves (wet but not dripping), put them in disposable paper cups, and put 1 piece in each paper cup. Put into 20 adult beetles of twenty-eight star ladybugs in each paper cup then, seal with gauze and rubber band, prevention and control escape. Each treatment was repeated 3 times, and the number of live worms was investigated after 1 day, 2 days, and 3 days, and the mortality rate was calculated.

[0032] The above-mentioned methods of use are respectively clear water (I), biogas slurry (II), 70% imidacloprid wettable powder 25000 times liquid (0.004% by weight) (III...

Embodiment 3

[0036] According to 4.5% beta-cypermethrin emulsifiable concentrate and 0.05% biogas slurry by weight, biogas slurry compound beta-cypermethrin insecticide is prepared, mixed evenly, put into a sprayer, and sprayed. Catch 2-4 instar cabbage caterpillars in the field and feed them uniformly with cabbage leaves. Select fresh and pest-free leaves, spray the front and back of the leaves (wet but not dripping), put them in disposable paper cups, and put 1 piece in each paper cup. Then put 15 cabbage caterpillars into each paper cup, seal with gauze and rubber band, prevent and escape. Each treatment was repeated 3 times, and the number of living adults was investigated after 1 day and 2 days, and the mortality rate was calculated.

[0037] The above-mentioned methods of treatment are clear water (I), biogas slurry (II), 4.5% beta-cypermethrin 2000 times solution (0.05% by weight) (III) (the recommended dosage for farmland is 700-2000 times solution), biogas slurry compounding Bet...

Abstract

The invention relates to compound biogas slurry insecticidal liquid and a preparation method. The insecticidal liquid is the compound biogas slurry insecticidal liquid which is prepared by a pesticide and biogas slurry in weight by percent: 0.02-0.2 percent of beta-cypermethrin and the biogas slurry, and 0.003-0.05 percent of imidacloprid and the biogas slurry. The preparation method comprises the following steps of: taking out the biogas slurry from a middle-layer discharging port of a biogas fermentation tank of which the biogas is normally fermented for over three months, wherein the total solid content of the biogas slurry is 10-12 percent; standing for 30 minutes; filtering to remove particle impurities to prepare the biogas slurry; reasonably mixing the biogas slurry and the beta-cypermethrin or the imidacloprid according to the weight percentage; fully stirring the mixture; and uniformly mixing. According to the compound biogas slurry insecticidal liquid and the preparation method, the biogas slurry generated in the anaerobic fermentation process of poultry excrement wastes is adopted, and the commonly-used insecticide is reasonably matched, so that common insect pests of a plurality of vegetable crops of kidney beans, eggplants, cabbages and the like can be effectively prevented; the insecticidal liquid is simple in preparation method, easy to operate and convenient to use, can reduce the using amount of the pesticides, and is suitable for being popularized; and the insecticidal liquid has the characteristics of efficiency, environment friendliness and low cost.

Description

technical field [0001] The invention relates to an insecticidal liquid and a preparation method in the technical field of pesticides, in particular to an insecticidal liquid with biogas slurry as the main component to compound pesticides. Background technique [0002] For a long time, the application of chemical pesticides has been the main means of controlling crop pests. Although chemical pesticides are effective in controlling pests, they cause certain harm to human health, biological safety and the ecological environment. At the same time, the long-term application of chemical pesticides induces the resistance of pests, resulting in a substantial increase in the amount of chemical pesticides, which is not conducive to the development of green products. Therefore, its dosage should be reduced as much as possible. It is an effective way to develop environmentally friendly pesticides or explore environmentally friendly pesticide application methods.
