Problems solved by technology

First of all, the abuse of chemical pesticides will increase the resistance of pests. It is reported that the effective use of conventional pesticides has tripled in ten years. If this continues, it is not alarmist that there is no cure for pests.
Secondly, although the application of chemical pesticides has increased the yield of crops, it is difficult to remove the residual chemical pesticides, which poses a great threat to human health
Finally, when the excess chemical pesticides flow into the river, it will seriously pollute the water quality. Not only can it be undrinkable, but it will also cause algal blooms and ecological imbalance.

Abstract

The invention discloses a natural organic pesticide composition and a preparation method thereof. The pesticide composition comprises the following components in parts by weight: 100 parts of neem leaves, 30 to 50 parts of pyrethrum, 18 to 28 parts of sweet wormwood, 20 to 30 parts of garlics, 20 to 30 parts of pepper and 5 to 15 parts of ginger. The preparation method comprises the following steps of weighing the neem leaves, the garlic, the pepper and the ginger in proportion, grinding, adding clear water, soaking for 12 to 24 hours, heating to 90 to 100 DEG C, keeping a slightly boiling state for 0.5 to 1 hour, filtering with heat, standing and cooling a filter liquor I, adding water to filter residues, soaking for 2 to 3 hours, boiling for 0.5 to 1 hour, then filtering again t obtain a filter liquor II, mixing two filter liquors, performing vacuum concentration at low temperature, so as to obtain a pesticide raw liquor, and diluting 1000 to 2000 times, so as to obtain the natural organic pesticide composition to be used. The pesticide composition disclosed by the invention has the advantage of wide insect resistant spectra and can be widely applied to planting nuisanceless plants, raw materials are natural and environmental, the pesticide composition is harmless to human bodies and environments, and the preparation method has the advantages of simplicity and easiness in implementation of industrialization.

Description

technical field [0001] The invention belongs to the technical field of pesticide production, and in particular relates to a natural organic pesticide composition and a preparation method thereof. Background technique [0002] In agricultural production, pests can interfere with the growth of crops, which not only affects the yield of crops, but also poses problems to food safety. Therefore, the vast majority of farmers will choose chemical pesticides to control pests. However, in recent years, the problems caused by the abuse of chemical pesticides have been paid more and more attention. First of all, the abuse of chemical pesticides will increase the resistance of pests. It is reported that the effective use of conventional pesticides has tripled in ten years. If this continues, it is not alarmist that there is no cure for pests. Secondly, although the application of chemical pesticides has increased the yield of crops, it is difficult to remove the residual chemical pest...
