Description
Technical field
The invention belongs to environment-protection pesticide technical fields, and in particular to a kind of green and environment-friendly pesticide and its preparation for rice
Method.
Background technique
With agrotechnical continuous development, for modern agriculture, pesticide occupied in entire agricultural system in not
Negligible position, pesticide are injured and are threatened to agriculture bring pest can objectively be greatly decreased, greatly improved and make produce
Amount, but pesticide is after spraying, and more pesticide can be remained on crop, will affect safe diet, induces diversified human body disease
Disease.Especially rice, in occupation of very big ratio in daily consumption, should more limit the pesticide that rice uses toxic has
The use of evil ingredient.And contain a variety of active ingredients in Activities of Some Plants extracting solution, there is pesticide-germicide effect, compared to common agriculture
Medicine has degradable, non-hazardous to human body feature, and does not pollute the environment and destroy the ecological balance.
The Chinese invention patent application of Publication No. CN106719947A discloses a kind of environment friendly biological formulation of pesticide, packet
Include the raw material of following parts by weight are as follows: 15-25 parts of mustard, capsicum 6-12 point, 3-10 parts of garlic, 20-30 parts of Chinese prickly ash, 10-20 parts of vinegar,
8-15 parts curried, 10-18 parts of ginger, 10-20 parts of Prunella vulgaris, 4-8 parts of lotus leaf, 20-35 parts of fennel, 7-15 parts of cortex cinnamomi, orange peel 8-
16 parts, 5-13 parts of cordate houttuynia, 2-6 parts of cape jasmine.The biological pesticide of invention preparation has significant synergies, and pest is not easy to produce
Raw resistance, can extend the service life of pesticide, expand the insecticidal spectrum of pesticide, reduce unit area dosage, control cost
It is low；The biological pesticide energy natural degradation, Environmental compatibility is good, so as to avoid the pesticide residue of agricultural product, agricultural product commodity
Property is good, price is high.But invention takes the extracting solution of plant as primary raw material completely, insecticide efficiency is compared to chemical pesticide
The disadvantage of still valid fruit difference, and extraction process is complicated, increased costs.
The Chinese invention patent application of Publication No. CN107810984A discloses a kind of environment-protection pesticide and its preparation side
Method, environment-protection pesticide are made of raw material from the following weight: 5-9 portions of hairyvein agrimonies, 3-8 parts of fin Jis, 5-10 parts of rhizobium powders, 6-15
