Abstract
The invention provides a process for preparing nimbin insecticide from the following constituents (by weight percent): roor of sessile stemona leachate 20-45%, tobacco stems and tobacco leaf leachate 25-50%, nimbin oil 5-35%. The process for preparing stemonine and tobacco stems leachate consists of disintegrating, water immersing, boiling, filtering and concentrating.
Description
Technical field
The present invention relates to pesticide field, specifically based on the insecticide preparation method of neem oil.
Background technology
Containing multiple desinsections such as nimbin, bitter principle in the well-known neem oil and press down the worm composition, is the biopesticide of pure natural, has efficient, wide spectrum, pollution-free, noresidue, is difficult for developing immunity to drugs, to person poultry harmless's advantage.Its weak point is can not play the effect that gets instant result to murdering of insect, generally needs can take effect through 2～3 talentes, therefore, seldom prepares insecticide separately with neem oil.
Summary of the invention
The purpose of this invention is to provide a kind of lasting medicine, have an insecticide that increases of quick insecticidal effect again.
The present invention is Main Ingredients and Appearance and pure natural, has the fast tuber of stemona leachate of insecticidal effect that by neem oil offal, tobacco leaf muscle leachate mix by a certain percentage, form through high-speed stirred.
(1) tuber of stemona leachate preparation method is: the tuber of stemona → pulverizing → water logging → boil → filter → concentrate.
(2) offal, tobacco leaf muscle leachate: offal, tobacco leaf muscle → pulverizing → water logging → boil → filter → concentrate.
Concrete mix proportion scheme of the present invention is: press main component and percentage by weight:
(1) tuber of stemona leachate: 20～45%;
(2) offal, tobacco leaf muscle leachate: 25～50%;
(3) neem oil: 5～35%;
Through fully stirring can at a high speed.
Advantage of the present invention is: the insecticide efficiency height, to environment do not produce pollution, noresidue, to person poultry safety, harmless.
Embodiment
Press main component and percentage by weight:
(4) tuber of stemona leachate: 20～45%;
(5) offal, tobacco leaf muscle leachate: 25～50%;
(6) neem oil: 5～35%;
Through fully stirring can at a high speed.
(1) tuber of stemona leachate preparation method is: the tuber of stemona → pulverizing → water logging → boil → filter → concentrate.
(2) offal, tobacco leaf muscle leachate: offal, tobacco leaf muscle → pulverizing → water logging → boil → filter → concentrate.
Claims (3)
1, a kind of method for preparing neem oil insecticidal agent is characterized in that:
Press main component and percentage by weight:
(1) tuber of stemona leachate: 20～45%;
(2) offal, tobacco leaf muscle leachate: 25～50%;
(3) neem oil: 5～35%;
Through fully stirring can at a high speed.
2, by the described method for preparing neem oil insecticidal agent of claim 1, it is characterized in that: tuber of stemona leachate preparation method is: the tuber of stemona → pulverizing → water logging → boil → filter → concentrate.
3, by the described method for preparing neem oil insecticidal agent of claim 1, it is characterized in that: offal, tobacco leaf muscle leachate: offal, tobacco leaf muscle → pulverizing → water logging → boil → filter → concentrate.
