Abstract
The invention relates to a pesticide preparation and process for preparing it, wherein the preparation mainly comprises nimbin and methylamino avermectin as t he active ingredients, and the preparation consists of mixing 0.05-20 wt% of nimbin extractive and 0.1-15 wt% of methylamino avermectin, at the presence of various auxiliary agents, preparing agricultural chemicals including emulsion oil, wet powder (WP), water granules (WG) and microcapsule suspending agent (CS).
Description
Technical field
The invention belongs to the composite insecticide of botanical pesticide and microbial pesticide, be specifically related to composite pesticidal preparations of nimbin and methylamino avermectin and preparation method thereof.
Background technology
Along with a large amount of unreasonable use of the particularly high malicious high residue product of chemical pesticide, in the stable and high yields of protection crops, also cause a series of problems such as environmental pollution, agricultural product residue of pesticide exceed standard, the increase of the sick Chinese caterpillar fungus pesticide resistance of crop inevitably.At these problems, people use the cry day of green bio agricultural chemicals more surging to exploitation, and the direct processing and utilization of natural products also becomes one of focus.By research, realized nimbin (extract) and methylamino avermectin composite, the invention of being processed into physics and stable chemical performance pesticidal preparations.
The seal chinaberry is one of plant insecticide of directly processing and utilization at present few in number, nimbin wherein has good biologically active to more than 10 purpose 200 various agricultural, warehouse and sanitary insect pests such as Lepidoptera, coleoptera, Homoptera, Semiptera, orthoptera, diptera, Hymenoptera, Blattaria, Phasmatodea, Isopteras, shows very high food refusal on using, avoids effect such as keep away, interior suction and inhibition are grown.It is low to have consumption, and degraded does not injure the characteristics of natural enemy and other non-target organism soon in environment.Because the diversity of mechanism of action, insect is difficult for developing immunity to drugs, and is the friendly type environment friendly agricultural of ideal environment kind comparatively.But the same with other most of botanical pesticides, seal chinaberry agricultural chemicals also exists the preparation processing difficulty, the product shelf life is short and weakness such as application quick-acting difference are asked in the field, makes its development be subjected to very big restriction.Processing about the nimbin pesticidal preparations, more bibliographical information is arranged both at home and abroad, but the chemical stability of failing to solve well product basically is the shelf life problem, such as micro nimbin emulsion, suspending agent, emulsifiable concentrate etc., just do not consider the lability factor of nimbin in water environment, be not suitable for being processed into water base property preparation.Obviously, these reports comprise that all there is bigger performance difficulty in patent documentation.
Methylamino avermectin is the low derivative that poisons of microbial source insecticide Avermectin, and its insecticidal activity is about 10 times of Avermectin, is desirable efficient, low toxicity, low-residue green biopesticide.But long-term single large tracts of land is used and is easy to generate pesticide resistance, thereby reduce the life cycle of product, be suspension of pesticide resistance generation, composite with chemical pesticide may be a kind of good selection, but the composite query that may make its Environmental compatibility be subjected to the chemical pesticide opposition person of biogenic pesticide and chemical pesticide.
Practice shows, the agricultural chemicals of different mechanism of action is by scientific and reasonable composite processing, can reach the expanding prevention scope, improves pharmacy effect, reduces drug cost, alleviates resistance risk, multiple purpose such as control resistant insect.According to producing actual needs, the present invention adopts plant insecticide neem extract and microbial source compound methylamino avermectin to be mixed, both can reach the purpose of mutual supplement with each other's advantages, can guarantee the green environmental protection of product again fully, can also reduce production costs greatly, reach the purpose that satisfies the agricultural production needs.
Take all factors into consideration according to former medicine physico chemical property and farmland instructions for use in view of pesticidal preparations processing and to select formulation.The present invention selects to help the stable formulations of pesticide of nimbin, specifically is missible oil (EC), wetting powder (WP), water dispersible granules (WG) or micro-capsule suspension (CS).Its reason is that missible oil product medium is an organic solvent, wetting powder, water dispersible granules are to be the solid pharmaceutical preparation of carrier with the inert filler, and seal chinaberry and the chemical stability of methylamino avermectin in organic solvent and inert carrier medium reach the Pesticidal products quality requirement.Micro-capsule suspension is nimbin to be coated with water-insoluble capsule leather material to form microcapsules earlier, and with the composite suspending agent that is processed into of methylamino avermectin, this formulation can guarantee that also product has good physics and chemical stability again.
The present invention has the following advantages and effect:
After nimbin and methylamino avermectin are mixed, both can overcome the slow shortcoming of nimbin insecticide effect, the advantage that can keep printing chinaberry insecticide long action time again.
