Abstract
The plant pesticide with natural avermectin microcapsule is prepared through adding synergist in 1-50 wt% into natural avermectin in 3-95 wt% to form the mixture, adding the mixture into dispersant aqua in 1-15 wt% through high efficiency mixture, adding wall material in 1-35 wt% at 35-60 deg.c for interface polymerization at stirring of 1500-2500 rpm for 30-60 min, further stirring at 600-1000 rpm for 25-35 min to obtain microcapsule, adding assistant in 1-30 wt% and carrier in 1-40 wt% into the microcapsule to prepare the plant pesticide microcapsule. The present invention may be used in organic food production and green food production to kill various pests in vegetable, Chinese medicine, flower, tea, etc.
Description
Technical field
The present invention relates to a kind of preparation method of plant pesticide, relate in particular to a kind of preparation method of natural pyrethrum plant pesticide.
Background technology
The human administration chemical pesticide has obtained the volume increase of agricultural product, solves food supply, performs meritorious deeds never to be obliterated.Find the insecticidal activity of DDT since nineteen thirty-seven Muller after, a large amount of organic phosphors, carbamates chemical synthetic pesticide have appearred successively, using in a large number for a long time of these toxic chemicals, caused the pollution of agricultural product, natural water, soil and atmosphere, useful insect disappears, harmful insect and the biological resistance that produces, many birds disappearances, ecotope are destroyed.Even more serious is remains of pesticide in crops and natural water, and wherein some is by directly endangering people and animals after the food chain enrichment.China is subjected to about 1,600 ten thousand hectares of the farmland of pesticide pollution, and residue of pesticide severe overweight in main farm produce, the particularly vegetables is greatly endangering the healthy of food security and people, and the agricultural chemicals residue problem is very outstanding in the agricultural products in China.Develop pollution-less agriculture, green agriculture, organic farming, become the inexorable trend of modernized agricultural development.Therefore, exploitation high-efficiency low-toxicity and eco-friendly botanical pesticide just arise at the historic moment.
12 kinds of biological insecticides have been recommended to the whole world by FAO (Food and Agriculture Organization of the United Nation), wherein have 9 kinds to be pyrethrin (pyrethrins) or pyrethroid chlorins compound.The Ministry of Agriculture allows in " the pollution-free food agricultural chemicals usage criteria " of in March, 2000 issue in the plant insecticide that A level, AA level pollution-free food use, and pyrethrin ranks first.Pyrethrin is by pyrethrins I, II, cinerin, II, the natural compounding type vegetable insecticide that six kinds of active insecticidal components of jasmolin I, II are formed has strong action of contace poison to the multiclass insect, in agriculture forest and husbandry production, grain storage and hygienic biocide field extensive use is arranged all.It is obtained by extracted form natural plant, and its leaching process and use are environmentally friendly, to the person poultry harmless, are considered to safe, the most effective natural plants insecticide in the world.
Chinese patent application 01145597.7 discloses a kind of natural pyrethrin missible oil preparation.Its preparation method is to use refined natural pyrethrosin primary medicine, the BHT or the tannin acid that add the 0.2-0.7% of pyrethrin content in the former medicine, fully behind the stirring and evenly mixing, the PB or the magnificent root of Chinese wild ginger that add the 6-10% of pyrethrin content in the former medicine again stir molten, the emulsifier that adds the 10-30% of pyrethrin content in the former medicine again adds the series natural pyrethrin emulsion preparation that an amount of benzinum gets different content again.This preparation has efficiently, noresidue, and pyrethrin resolves into water and carbonic acid gas at occurring in nature, the characteristics that toxicity is extremely low.But, the preparation of this method preparation has the following disadvantages: 1. the main insecticidal activity composition in this preparation is easily decomposed by daylight, air, higher temperature and metal ion in accumulating, application, especially the strongest with the ultraviolet light degradation effect, thus cause the drug effect phase short, and it is higher to use cost.2. there is the organic solvent benzinum in its preparation, harmful to environment, thus weakened the environment-friendly advantage of botanical pesticide.
Summary of the invention
The product of the inventive method preparation has overcome the deficiency of above product, provide a kind of insecticidal activity composition be difficult for decomposing, drug effect is long, uses that cost is low and the preparation method of the plant pesticide that the environment blending is good.

Consolidated statement 1-2 analyzes as can be known: each processed group difference compared with the control is more obvious.The processed group C drug effect lasting period is obviously long than processed group B.
Compare by analysis, C2 group concentration intends electing as the concentration of next step vegetable aphid insecticidal test.
4 brief summaries
Directly spray cauliflower aphid particular significant effect 4.1 use 3% natural pyrethrum microcapsule formulations.Since microcapsule formulations by slow releasing function in acceptor, reduced light, air, water and microorganism in the environment to the decomposition of agricultural chemicals, reduced that volatile flow becomes estranged mutual chemical reaction may, and changed release performance, thereby prolonged the lasting period, spraying time widens at interval, on the other hand, reduced to the pollution of environment with to the poisoning of crops.
4.2 the proterties that is reflected by the cauliflower aphid of handling: insecticidal effect and microcapsule formulations concentration are proportionate, i.e. high concentration polypide lethality height, and the death time lacks, and low concentration polypide lethality is low, and the death time is long.The result shows from field experiment: intend selecting the concentration of 1: 2500 times of concentration for next step land for growing field crops insecticidal test.
4.3 desinsection time insecticidal effect between fine 12～18 o'clock is remarkable.Its reason: 1, no dew can not influence the concentration of soup on the cauliflower plant.2, low, the high polypide body surface of the temperature drying of air humidity, the direct injection polypide helps the infiltration of soup, quickens the dead time limit.
4.4 this test also exists many unsatisfactory places, as knowledge such as the life habit of cauliflower aphid, fertility characteristic, pests occurence rule are understood not exclusively, it is constantly perfect to remain next step test of pesticide effectiveness.
