Description
Technical field
The present invention relates to pesticide field, be specifically related to a kind of rice sheath blight disease mancozeb combined Chinese herb bactericide of preventing and treating.
Background technology
Rice sheath blight disease claims again moire disease, and popular name is spent sufficient stalk, rotten pin pest, features spot.Be to infect and fall ill by Rhizoctonia solani Kuhn, how occur under high temperature, super-humid conditions.Banded sclerotial blight causes harm seriously at South Rice Region of China, is one of Major Diseases on current Rice Production.This disease can not be eared paddy rice, or the not plump paddy of heading is more, and grain heavily descends.Existing control medicament mostly is the pure chemistry medicament, and the use of pure chemistry medicament has the efficient while, exists price high, the shortcoming that sick worm easily develops immunity to drugs.The invention provides the built agent that a kind of a small amount of chemical agent and combined Chinese herb are made, good disinsection effect, environmental protection, do not develop immunity to drugs.
Summary of the invention
The objective of the invention is just to be to provide a kind of mancozeb combined Chinese herb bactericide of preventing and treating the rice sheath blight disease damage by disease and insect, this composite bactericide has desinsection, repellent, food refusal, stomach toxicity, action of contace poison, is a kind of efficient, low toxicity, environmental-friendly plant bactericide.
The present invention adopts following technical scheme in order to achieve the above object:
A kind of mancozeb combined Chinese herb bactericide of preventing and treating the rice sheath blight disease damage by disease and insect, it is characterized in that: its every 100 parts of built agents are made by the raw material of following weight portion: mancozeb 8-12, Celastrus angulatus 9-11, chameajasme 9-11, kuh-seng 9-11, golden cypress 4-6, rhizome of cyrtomium 4-6, datura flower 4-6, Chinese pulsatilla 4-6, root of large-flowered skullcap 4-6, monkshood 4-6, betel nut 2-3, frutus cnidii 2-3, dayflower 2-3, kaladana 2-3, honeycomb 2-3, pine needle 2-3, tuber of stemona 2-3, thunder godvine 2-3, black false hellebore 4-6, all the other are auxiliary material
Wherein, every kind of Chinese herbal medicine is all allocated bactericide into the form of extract of water extract or organic solvent after water extraction or organic solvent extraction.
The described mancozeb combined Chinese herb bactericide of preventing and treating the rice sheath blight disease damage by disease and insect, it is characterized in that: the formulation of described mancozeb combined Chinese herb bactericide is oil-suspending agent.
The described mancozeb combined Chinese herb bactericide of preventing and treating the rice sheath blight disease damage by disease and insect, it is characterized in that: the carrier of described oil-suspending agent is turpentine-based vegetable oil.
Bactericide of the present invention also can be made into other formulation.
Preparation method: by formula rate, take each component raw material, the various herbal raw material that take are mixed, then extract active ingredient by water extraction or organic solvent extraction method, will mix with mancozeb after the extract drying, making the regular dosage form of various built agents according to conventional method.
Using method: in the rice sheath blight disease their early stage, 800-1000 times of dilution, foliar spray.
Beneficial effect of the present invention:
Composite bactericide of the present invention has insecticidal action Chinese herbal medicine active component and a small amount of composite forming of mancozeb by multiple, for preventing and treating the rice sheath blight disease damage by disease and insect, rapidly and efficiently, have simultaneously and tag and stomach poison function, can benumb the insect nerve center, solidify polypide protein, stop up the polypide pore, kill off the insect pests; Active ingredient by rice absorbing after, progressively metabolism is decomposed, and can not produce enrichment phenomenon, noresidue, can not pollute environment, do not injure pest natural enemy, can effectively preserve the ecological environment; It comes from the Nature, and rice banded sclerotial blight disease and insect centering grass agricultural chemicals can not develop immunity to drugs, and control efficiency is good.
