Abstract
The present invention relates to a kind of Camptothecines plant insecticide and manufacture method thereof.The component of this insecticide comprises (weight %): camptothecine 33～36%, bugle alkali 3～5%, wilfordine 7～12%, drooping stringbush flower root and bark alkali 3～6%, palmatine base 1～3%, Bothriospermum Chinese 1～2%, additive 5～11%, water 30～36%.The manufacture method of this insecticide is: at first with each material coarse cutting, mix by a certain percentage; Next is dried, and pulverizes, and leaching is filtered, and is mixed; Last can, warehouse-in.This insecticide is pollution-free, and no residual hazard has good disinsection effect, the characteristics that insect can not develop immunity to drugs; Its manufacture method is simple, suitability for industrialized production.
Description
The present invention relates to a kind of insecticide and manufacture method thereof that contains the various plants extract, especially a kind of is the vegetable insecticide and the manufacture method thereof of main component with the camptothecine.
At present, agriculture employed agricultural chemicals polyphyly chemicals is no matter how dispenser all is that agricultural chemicals is spread to occurring in nature.With the sprinkling is example, attaches generally only having about 30% on the crop, and all the other major parts fall into soil, and what the agricultural chemicals in the soil had can be by plant absorbing, and what have then enters the waters with rain drop erosion, causes environmental pollution.The chemical pesticide less stable, and residual hazard is big, and the people has eaten grain, the vegetables of band toxicity, gently then causes chronic poisoning, heavy then carcinogenic, teratogenesis.In recent years, for reducing the prestige evil of chemical pesticide residual hazard to people and animals, agricultural chemicals scientific research department has carried out the development of agricultural chemical of natural plant both at home and abroad, as toosendanin, rhododendron toxin, and Celangulin, Tea Saponin etc., these product major parts are not carried out field experiment, more do not carry out suitability for industrialized production, small part is owing to technological requirement height, equipment complexity, unsuitable suitability for industrialized production, thereby the large tracts of land of failing is promoted.
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art and to provide a kind of be primary raw material with the camptothecine, to the person poultry harmless, has good insecticidal effect through the field experiment proof, and manufacture method is simple, is easy to the vegetable insecticide of suitability for industrialized production.
Technical solution of the present invention is: Camptothecines plant insecticide contains following component (weight %):
Camptothecine 33～36%
Bugle alkali 3～5%
Wilfordine 7～12%
Drooping stringbush flower root and bark alkali 3～6%
Palmatine base 1～3%
Bothriospermum Chinese 1～2%
Additive 5～11%
Water 30～36%
In order to prevent that the present composition from bubbling, and can also contain 1～2%(weight % in above-mentioned composition) methyl-silicone oil as defoaming agent.
Can also contain 1～2%(weight % in the present composition) Sodium Benzoate as mould inhibitor.
The used additive of the present invention is 0
#Diesel oil.
The manufacture method of Camptothecines plant insecticide is: at first camplotheca acuminata, horn, thunder godvine, drooping stringbush flower root and bark, herba fibraureae recisae, Bothriospermum Chinese are cut into slices respectively, coarse crushing, then with above-mentioned raw materials successively with 7～12: 1～2: 1～3: 1: 1: 1 ratio (weight) is mixed, then with this mixture oven dry, moisture is controlled at≤and 6%, again siccative is pulverized, crossed 30～40 mesh sieves; Secondly place leaching can to leach 12～24 hours powder, filter then, the pH value of regulating filtrate is 7～9, and the jar that then filtrate packing into is mixed adds additive simultaneously and also constantly stirs; Last can, warehouse-in.
Compared with prior art, the present invention has the following advantages:
1, pollution-free, no residual hazard has been eliminated agricultural chemicals to the pollution of environment with to the threat of human health.
2, have the composite insecticidal composition, the desinsection scope is wide, and drug effect is long, and insect can not develop immunity to drugs.
3, raw material is easy to get, and cost is low, and manufacture method is simple, suitability for industrialized production.
The invention will be further described below in conjunction with embodiment:
Embodiment:
Camptothecines plant insecticide (weight %) composed of the following components: camptothecine 34%, bugle alkali 4%, wilfordine 9%, drooping stringbush flower root and bark alkali 5%, palmatine base 2%, Bothriospermum Chinese 1.5%, additive 7%, defoaming agent 1.5%, mould inhibitor 1.5%, water 34.5%.
The manufacture method of Camptothecines plant insecticide is as follows: the first step: with camplotheca acuminata, horn, thunder godvine, drooping stringbush flower root and bark, herba fibraureae recisae, Bothriospermum Chinese, section respectively, coarse crushing, then with above-mentioned raw materials successively with 8: 1: 2: 1: 1: 1 ratio (weight) is mixed; Second step: with the said mixture oven dry, moisture is controlled at 2%, advances attrition mill and pulverizes, and crosses 30 mesh sieves; The 3rd step: powder is placed leaching can leaching 12 hours, filter then, the pH value of regulating filtrate is 7; In the 4th step, the filter pump that mixes up pH value squeezed into be mixed jar and constantly stir, meanwhile, add additive 7%(weight), defoaming agent 1.5%(weight), mould inhibitor 1.5%(weight %); The 5th step: can, warehouse-in.
