Description
Technical field
The present invention relates to a kind of agricultural insecticide, specifically a kind of spiral shell worm ethyl ester containing mineral oil dispersibles oily suspension
Agent and preparation method thereof, application, belong to chemical pesticide manufacture field.
Background technology
Spiral shell worm ethyl ester, English name Spirotetramat, chemical name：4- (ethoxy carbonyl epoxide) -8- methoxyl group -3-
(2,5- xylyls) -1- azaspiros [4,5]-decyl- 3- alkene -2- ketone.High-efficient broad-spectrum insecticide, for preventing and treating multiple pierce-suck type mouths
Device insect；Interior suction, Bidirectional Conduction can protect cambium and root；Lasting period is long, and long-time is invaded by cover crop from insect
Evil；Research shows which there is good selectivity, suitable integrated pest to control important beneficial insect such as ladybug, wasp fly and parasitic wasp
Reason.Spiral shell worm ethyl ester has unique function Characteristics, is the modern pesticides uniquely so far with two-way Uptake and translocation performance.The change
Compound can be moved down in whole plant upwards, arrive at blade face and bark, so as to prevent and treat as on romaine lettuce and Chinese cabbage internal lobe,
And the insect in skin of fruit tree.This unique interior suction performance can protect newborn stem, leaf and root, prevent ovum and the larva of insect
Growth；Its another feature was that the lasting period is long, it is possible to provide up to effective preventing and treating of 8 weeks.In addition to the efficient effect to scale insect,
Also simultaneously to red spider, aphid (eriosoma lanigerum, citrus aphid, black peach aphid, radicola), wood louse, pear sucker, aleyrodid, thrips (flower thrips,
Scirothrips dorsalis, onion thrips) etc. pierce-suck type implication insect there is outstanding preventive effect.
Mineral oil, can form oil film on polypide with pesticide compositional, and wick into ovum pore and
Larva, pupa, the valve of adult and tracheae, suppressed by suffocating insect and acarid dead they.Each stage that it is grown to worm mite
All work, including the stage of ovum.For the fixed and slow small worm smothering effect of movement ideal (as mite class, scale insect,
Part aphid and aleyrodid), and natural enemy is very active, the therefore impact to natural enemy is very little.Mineral oil can penetrate chorion, do
The metabolism of ovum and the effect of respiratory system is disturbed, ovicidal has for fulminant insects such as control Bemisia tabaci, trialeurodes vaporariorum, diamondback moths
Greatly it is worth.Furthermore it is possible to change insect behavior, show as spawning is greatly reduced, take food, mate.Generally, phytophagous elder brother
Worm and mite class only can take food on some specific plants and lay eggs, and they are visited with the perceptron of feeler, mouthpart, foot or belly
The chemical substance of host plant is surveyed, so as to recognize plant.After oil film covers sense organ and plant surface, insect cannot just be distinguished
Know host plant, which reduces insect and on host plant take food and lay eggs.To citrus red mite, spawning rate declines 90%
More than；To leaf miner, Liriomyza, diamondback moth, effective decline of spawning rate is all showed.Mineral oil affects the meaning of pests
Very big, the function of protection plant in the case where them are not killed, is played, these insects have flea beetle, aleyrodid, aphid.Insect
Feeler is covered by oil, then directly affect insect behavior, is such as mated, and is had been found that in some experiments, that is, change insect behavior, directly
Connect reduction pest population, cover crop.
It is that by pesticide original medicine and various auxiliary agents, (emulsifying agent, feature are helped with oil as decentralized medium to dispersible oil-suspending agent
Agent, inert filler etc.) obtain through soybean dietary fiber high dispersive, stable pesticidal preparations.Dispersible oil-suspending agent water dilute
Release to be sprayed on plant and easily form one layer of medicine film, because plant surface has wax coat, according to similar compatibility principle, permeate conductibility
By force, adherence is good, resistance of rainwater washing against, and drug effect is played more preferably, and utilization rate of active components is high, and formulation environmental protection.Although dispersible
Property oil-suspending agent have many good qualities, but high to technical requirements, it is difficult to be configured to stablize qualified product, at present the agent of registration
Type product mostly is corn, wheat field herbicide, and registers on insecticide less.
To adult, larva, nymph and ovum effectively, for adult, larva, nymph, spiral shell worm ethyl ester must elder generation's quilt for spiral shell worm ethyl ester
Plant leaf blade absorbs, redistribution, then by action in insect suction body, so the absorption of spiral shell worm ethyl ester is into premised on.Commercially available
Because being aqueous suspension agent, the absorption of plant is its weakness to 240g/L spiral shell worm ethyl esters, so the selection of formulation and the design of formula are aobvious
Obtain particularly critical.Link drug effect is poor because majority does not account for absorbing for home products, and although apparent index is very for some preparations
Good but active ingredient is not sucked by blade face well.Spiral shell worm ethyl ester is general for adult toxicity, but which can be affected to lay eggs,
Even if output, ovum can not normal development.For ovum, medicine is worked by being infected with chorion, and this requires that the medicine that applies exists
It is evenly distributed on plant.
