Abstract
The present invention relates to pesticide dry powder insecticide for plants, which is manufactured by raw medicine material of the following percentage by weight: 5 to 85% of puberulent monkshood root stem and leaf, 5 to 85% of cortex dictamni radices, 5 to 85% of hylonoma euphorbia root, and 5 to 75% of sungpan aconite. The present invention has a preparation method that plant coarse powder is mixed according to the percentage by weight, the coarse powder after being mixed is extracted by solvent to manufacture extracting solutions of plant substances with insecticidal activity, and finally, the extracting solutions of plant substances with insecticidal activity are manufactured into dry powder insecticide in a spraying and drying method. The present invention takes insecticidal plants in Qinling mountainous areas as raw material and utilizes components with the insecticidal activity in original plants for preventing and curing pests, and green pesticide dry powder insecticide containing alkaloid is manufactured through scientific formulation, separation, purification, spray and dryness. The pesticide dry powder insecticide is mainly used for preventing and curing the pests of economic crops, such as vegetables, watermelons, corn, etc., and integrated preventing and curing effect can achieve more than 85%.
Description
Technical field
The present invention relates to a kind of plant pesticide dry powder insecticide and preparation method thereof.
Background technology
Chemical pesticide makes a great contribution for the mankind, but in today that its toxic and side effect more and more exposes, it is more and more important that the research and development of plant pesticide just seem.Plant pesticide of the prior art is liquid state, less stable, and be not easy to storage and transport.
Summary of the invention
Technical problem to be solved by this invention: a kind of plant pesticide dry powder insecticide and preparation method thereof is provided, pesticide plant with mountain area, the Qinling Mountains is a raw material, utilize the active insecticidal components in the former plant to carry out control of insect, composite through science, separation and purification, atomized drying is made a kind of environment friendly agricultural dry powder insecticide, and its main active insecticidal components is an alkaloid, reaches the purpose that suppresses insect by food refusal, stomach poison function.Be mainly used in economic crops insects such as control vegetables, watermelon, corn, integrated control effect can reach more than 85%.
Technical solution of the present invention:
The present invention is made by the following raw materials by weight percent medicine: flat (being commonly called as pigtail root seven) 5～85% of ox, dittany bark 5～85% makes 5～85% for nine Ns, sungpan monkshood root 5～75%.
Preparation method of the present invention: at first each plant meal is mixed by above-mentioned percentage by weight, then mixed meal is made plant insecticide active substance extract with solvent extraction, at last plant insecticide active substance extract is made the dry powder insecticide by spray drying process.
For guarantee insecticide active substance can be fully, be suggested effectively, therefore can consider under ultrasonic state with solvent extraction plant insecticide active substance extract, described solvent is the second alcohol and water, can be dissolved in the plant insecticide active substance proposition of organic solvent earlier with ethanol, water extracts the plant insecticide active substance again, and plant insecticide active substance extract is made in the merging of said extracted liquid.
Advantage of the present invention and effect:
1, good water solubility of the present invention all has lethal effect preferably to mythimna separata, grasshopper, cricket, cabbage caterpillar and aphid; Virulence experiment shows food refusal rate to insect all more than 97%, and lethality all (is adopting leaflet butterfly additive process to measure) more than 79%; Meet light in 24 hours, meet heat and still can keep stronger insecticidal action; Integrated control effect can reach more than 85%.
2, compare therapy in dry powder form with liquid plant pesticide and be convenient to transportation, be easy to preserve, good water solubility has been saved packing, transportation and inventory carrying cost, has also prolonged the storage life of plant pesticide simultaneously.
3, each component synergy, it is very inviolent to have toxic action, the distinguishing feature that the food refusal rate is high, after the dispenser, easily degraded, low toxicity is to the person poultry harmless, with environmentally compatible.
Embodiment
1, material medicine proportioning (percentage by weight):
