Abstract

The present invention provides a mixed nimbin pesticide having the advantages of high efficiency, low toxicity, no pollution, no harm to human and livestock, and low possibility of pesticide resistance generated by pests. In the mixed nimbin pesticide, the synergistic effect and the negative cross resistance relationship between the active components of nimbin and Bt are used for overcoming the pesticide resistance of pests, enhancing the application effect of the pesticide, and enlarging the application range of the pesticide. The deficiencies of the single-agent pesticides can be overcome owning to the synergistic effect of the components of the mixed nimbin pesticide in the application process. The pesticide is particularly suitable for controlling various pests with strong pesticide resistance.

Description

The pesticidal preparations that nimbin and Bt are mixed
The invention belongs to a kind of mixed insecticide, particularly, relate to nimbin how with other insecticide mixtures.
Because people rely the insecticide that uses a certain type in the chief of the Xiongnu in Acient China for a long time, insect is easy to generate pesticide resistance, causes the chemical dosage of insecticide sharply to increase, and not only increases the weight of peasant's financial burden, contaminated environment, and because the natural enemy of a large amount of kill pests causes the wildness harm of insect.Have a large amount of mixed insecticides in the market, but the overwhelming majority is being mixed between the chemical pesticide, these mixtures mostly contain organic phosphates, toxicity to people and animals is bigger, easily cause the person poultry poisoning, and after the long period used, insect can develop immunity to drugs also.
The objective of the invention is to develop a class is active insecticidal components with the nimbin in the plant neem seed, and after reasonably being mixed with Bt insecticide efficient, low toxicity, acquisition can overcome the nimbin mixed pesticide preparation of pest resistance to insecticide.
The present invention utilizes neem seed to carry out lixiviate, becomes to contain certain density nimbin extract, and extract becomes concentrate after concentrating evaporate to dryness.
The present invention utilizes the nimbin in the plant neem seed to be active insecticidal components, by being mixed with biopesticide Bt, and allocating appropriate amount of addition agent into and is prepared into mixed insecticide nimbin+Bt wettable powder agent formulation.
Each component content proportioning is in mixed insecticide nimbin+Bt wettable powder agent formulation: nimbin content is 0.1-35% (weight); Bt content content is 0.5-50% (weight); Wetting agent content is 1-20% (weight); Dispersant is 7-30% (weight); Antiseptic content is 0.1-2.9% (weight); Filer content is 15-75% (weight); Each component summation is 100%.
Wetting agent component in mixed insecticide nimbin+Bt wettable powder agent formulation is to be selected from: lignosulfonates, alkylbenzenesulfonate, draw back in powder, the multi-sorbitol ester any one or more; The dispersant component is to be selected from: naphthalene sulfonate, alkylsulfonate, polyoxy ethyl ether sulfonate, diisopropyl phosphate any one or more; Preservative component is to be selected from: active carbon, alkaline earth metal any one or more; Filler component is to be selected from: kaolin, diatomite, active carbon any one or more.
The optimal proportion of each component content is in mixed insecticide nimbin+Bt wettable powder agent formulation: nimbin content is 0.3-20% (weight); Bt content is 1-1.5% (weight); Wetting agent content is 5-15% (weight); Dispersant is 10-25% (weight); Antiseptic content is 1-1.5% (weight); Filer content is 45-65% (weight); Each component summation is 100%.
Mixed insecticide nimbin+Bt wettable powder agent formulation adopts conventional pesticide wettable processing technology to get final product in preparation process.

Beneficial effect of the present invention is as follows:
1. the present invention is in preparation nimbin+Bt wettable powder agent formulation process, by adding the multiple choosing that supplies With wetting agent, dispersant, anticorrisive agent and filler, system has deeply solved nimbin+Bt can The difficult problems such as poor, the easy pollution of WP preparation dispersive property.
2. after nimbin and Bt are mixed in aforementioned selected ratio, the numerous of biological pesticide itself have not only been kept Advantage, and the reduction of the dosage of mixture, drug effect increases substantially, and has remedied the nimbin plant The insects agent is to the weakness of lepidoptera pest stomach poison function weak effect. This mixture is to natural insecticide Application and Development have profound significance.
3. nimbin belongs to the different pesticide of two class mechanism of action from Bt, and the nimbin+Bt after being mixed can The WP preparation has not only enlarged the control of insect spectrum, and has more uniform to simultaneous insect Drug effect, thus delay even overcome the resistance to the action of a drug that may become sociales after the pest population succession. Should Mixture application effect in the resistance diamondback moth governance process on to vegetables is particularly remarkable.
Since the preparation nimbin+required each material of Bt wettable powder agent formulation compatibility and reasonable mixture ratio, Can greatly alleviate the toxic action to the various pest natural enemies of kill, to the infringement of ecological environment and Less pollution is conducive to protect the person poultry safety. Be that a class can be prevented and treated multiple agriculture and forestry injurious insect, poison is paid Act on littlely, and can overcome the nimbin mixture of pest resistance to insecticide.
