Abstract
The invention relates to a pesticide preparation and a preparation method thereof, particularly a suspending agent containing abamectin and spirotetramat and a preparation method thereof. The suspending agent is composed of the following components in percentage by mass: 0.1-40% of abamectin, 0.1-40% of spirotetramat, 0.5-15% of wetting and dispersing agent, 0-12% of antifreeze agent, 0.1-1.5% of thickener, 0.1-1% of defoaming agent, 0.1-5% of antimicrobial agent, a right amount of pH regulator and the balance of deionized water. The suspending agent has the characteristics of stronger synergistic action and high pesticidal speed, lowers the toxicity, widens the pesticidal spectrum, reduces the unit area consumption, lowers the use cost, and is beneficial to environmental protection. The suspending agent can prevent and treat Noctuidae, Carposina, Tortricid, Ephestia and the like in Lepidoptera, and has an obviously higher effect than a single agent.
Description
Technical field
The present invention relates to a kind of pesticidal preparations and preparation method thereof, specifically a kind of suspending agent containing Avermectin and spiral shell worm ethyl ester and preparation method thereof.
Background technology
Along with the enhancing gradually of people's environmental consciousness, increasing to the demand of the environmental protection type agricultural chemical of efficient, low toxicity, low-residual, agricultural chemicals scientific workers are making great efforts that exploitation is efficient, low toxicity, the pesticide new variety of environmental protection, novel form.
Avermectin structural formula:
Physicochemical property: Avermectin, former medicine fine powder is white or yellow crystal (containing B1a >=90%), vapour pressure <200nPa, 155 ℃ of fusing point 150-, in the time of 21 ℃ solvability in water in 7.8 micrograms per litre, acetone 100, in toluene 350, isopropyl alcohol 70, under chloroform 25 (g/L) normal temperature, be difficult for decomposing.At 25 ℃, in the solution of pH5-9 without decomposing phenomenon.
The Avermectin mechanism of action is to disturb neurophysiology movable, stimulate and discharge r-aminobutyric acid, and r-aminobutyric acid there is inhibitory action to arthropodan nerve conduction, if mite class occurs paralysis symptom after becoming mite to contact with medicament with larva with insect, inertia does not take food, dead after 2-4 days.Because not causing that insect dewaters rapidly, so its lethal effect is slower.Tag, stomach toxicity, penetration is strong.Avermectin high-efficiency broad spectrum, parasitic red worm, diptera, coleoptera, Lepidoptera and pest mite etc. all have good control effect.
Spiral shell worm ethyl ester chemical name: 4-(ethoxy carbonyl oxygen base)-8-methoxyl group-3-(2,5-xylyl)-1-azaspiro [4,5]-last of the ten Heavenly stems-3-alkene-2-ketone.
Physicochemical property: former medicine outward appearance is white powder, without special smell, preparation outward appearance is tool fragranced white suspension.142 ℃ of molten points, solvability (20 ℃) water 33.4mg/L, organic solvent: ethanol 44.0mg/L, n-hexane 0.055mg/L, toluene 60mg/L, carrene >600mg/L, acetone 100-120mg/L/ ethyl acetate 67mg/L, dimethyl sulfoxide (DMSO) 200-300mg/L.235 ℃ of decomposition temperatures. stability is better.
Spiral shell worm ethyl ester is a kind of Novel special window acids insecticide, and insecticidal spectrum is wide, and the lasting period is long.It is that fatty biosynthesis by interference insect causes larva dead, reduces the fertility of adult.Due to its unique mechanism of action, can effectively prevent and treat the insect that existing insecticide is produced to resistance, can be used as the important kind of nicotinic insecticide resistance management simultaneously.Effectively control sucking pest.
