Technical field:
The invention belongs to technical field of pesticide, be specifically related to a kind of pyrrole aphid ketone microemulsion, be used for the control of water rice hopper, wheat aphid, brassicaceous vegetable aphid.
Background technology:
Great changes have taken place in global in recent years agricultural chemicals policy, particularly developed country is very strict to the use restriction of high poison, persistent pesticide, particularly played the whole nation on January 1st, 2007 and forbid that high malicious persistent pesticide uses on agricultural, with increasing, and high poison, high residue type pesticide species will eliminating by mercilessness under the effect of forbidding order to the demand of the environmental protection type agricultural chemical of efficient, low toxicity, low-residual in the domestic market.For a long time, emulsifiable concentrates for agricultural chemicals is the important formulation of pesticidal preparations always, but owing to contain a large amount of inflammable organic solvents in the missible oil, had relatively high expectations in aspects such as production, storing and use, particularly in long-term use, a large amount of organic solvents evaporate in the atmosphere, and environment has been caused serious pollution, and all these problems have caused people's extensive concern.
Pyrrole aphid ketone English name: (pymetrozine), molecular formula: C
10H
11N
5O, chemical name: 4,5-dihydro-6-methyl-4-(3-pyridine methylene amino)-1,2,4-3 (2H)-ketone,
Structure be for:
Pyrrole aphid ketone is a kind of sucking pest to be had the very efficient novel insecticide of high selectivity, is mainly used in Bemisia tabaci, the control of insects such as thrips, aphid, trialeurodes vaporariorum, leafhopper, rice fulgorid.Controlling insects such as aphid, plant hopper and trialeurodes vaporariorum on crops field, vegetables field, ornamental plants, fruit tree just is used widely.
Summary of the invention
The objective of the invention is to announce a kind of pest killing micro emulsion that contains pyrrole aphid ketone, this microemulsion is used for the control of water rice hopper, wheat aphid, brassicaceous vegetable aphid.
Another object of the present invention provide a kind of safe, the feature of environmental protection good, lower-cost pest killing micro emulsion.
The objective of the invention is to be achieved through the following technical solutions:

Described pyrrole aphid ketone microemulsion is produced by following steps:
(1) the former medicine of pyrrole aphid ketone is dissolved in the homogenizer that solvent and cosolvent are housed;
(2) mix strongly after joining emulsifier, stabilizing agent and antifreeze, water in the homogenizer that above-mentioned solution is housed and homogenize, obtain the as clear as crystal pyrrole aphid ketone microemulsion of outward appearance at last.
Compared with prior art, the present invention has the following advantages:
(1) the pyrrole aphid ketone microemulsion of the present invention's preparation has reduced the consumption of organic solvent significantly, has reduced the pollution to environment, has improved the safety to the producer, transporter, user.
(2) conventional cream preparation is mixed with when spraying emulsion, and its oil droplet fineness is 0.1～1.0 micron, and its oil droplet fineness of sprinkling emulsion of microemulsion preparation is 0.005～0.01 micron, is lower than 0.005 micron and has approached true solution.Therefore the present invention has improved pesticide active ingredient pyrrole aphid ketone and the dispersity of composite adjuvant in emulsion thereof, makes emulsion approach true solution, thereby has strengthened the penetrating ability of pyrrole aphid ketone to insect pest of the plant, has improved control efficiency, has improved availability simultaneously.
