Abstract
The invention discloses a kind of second azoles mite nitrile and the Pesticidal combination of diafenthiuron, show by the screening of substantial amounts of toxicity and field control effectiveness test, the Pesticidal combination is 1 in compound proportion in second azoles mite nitrile and diafenthiuron:20‑20:Preventive effect when 1 to citrus red mite shows obvious synergistic function.Pesticidal combination prevention effect of the invention is good, consumption is low, to crop and beneficial natural enemies security, is worth the popularization and application in production.
Description
Technical field
The invention belongs to agricultural insecticide compositions field, and in particular to be a kind of mite nitrile of azoles containing second and diafenthiuron desinsection
Composition and application thereof.
Background technology
Mite class is commonly called as red spider, belongs to arachnoide pest, is various cause harm fruit tree, cotton, Solanaceae, vegetables and ornamental flower etc.
One of important pests of crop, belong to Acariformes and Acarina common evil mite more.Mite class mainly causes harm leaf, stem and the flower of plant
Deng, the cauline leaf for inhaling plant is pierced, there is the yellowish-brown dot of a large amount of needle point size chlorosis in initial stage leaf front, and anaphase blade is opened from the bottom up
Beginning chlorosis is crispaturaed, is even come off.Sometimes from plant middle part, blade takes place, and blade gradually turns yellow, comes off.Evil mite occurs from generation to generation
Many, fertility is strong, under suitable temperature and humidity conditions, mite population can be doubled and redoubled rapidly within a short period of time, to agriculture
Crop causes very big harm.Evil mite is also easy to produce the resistance to the action of a drug to mite killing medicament, if do not prevented and treated in time in serious generation, aggrieved work
The blade meeting chlorosis of thing is turned white, and is withered and fallen in advance.Under the torrid zone and greenhouse experiment, whole year can all occur.The height of temperature is determined
The number of the growth cycle, reproduction speed and egg laying amount of each worm state of mite class.It is big that the weather conditions of extreme arid torrid climate frequently can lead to its
Amount occurs.
The new acaricide of second Zuo Manjingshi China independent intellectual property right, Shenyang Sciencreat Chemicals Co., Ltd. develops
30% second azoles mite nitrile suspending agent product.Second azoles mite nitrile quite tires out such as panonychus citri, oranges and tangerines to phytophagous and embroiders mite, apple tetranychus, cotton
Tetranychid, eggplant tetranychid etc. show high activity, have preferable therapeutic effect to each period of acarid.
Diafenthiuron is a kind of new sulfur ureas efficient insecticide, acaricide, with tagging, stomach toxicity, interior suction and fumigation action, and
With certain ovicidal effect.It is changed into the material with insecticidal activity under ultraviolet light, to having produced serious anti-medicine on vegetables
Property insect have stronger activity.Aphid, aleyrodid, leafhopper, the noctuidae pests in various crop and ornamental plant can be prevented and treated
And evil mite.
Chemical prevention medicament should also need to the lasting period more long with quick-acting, and single medicament continuously uses appearance
Pest resistance to insecticide generation is easily caused, so that prevention effect declines substantially.Rational pest control with insecticide acaricide compounding or mixture have
Expansion prevents spectrum, improves prevention effect, extension optimum period for applying fertilizer, reduces dosage, reduce poisoning, reduce residual, delay insect resistance to
The positive feature such as the property of medicine and drug-fast generation and development, insecticidal/acaricidal agent compounding or mixture are having the most of solving the above problems
One of method of effect.Develop new product insecticide price constantly rises, and by contrast, exploitation is efficient with research, low toxicity, low-residual
Compounding there is small investment with mixture, the lead time is short and paid attention to both at home and abroad, numerous and confused increasing develops dynamics.
Present inventor is had found second azoles mite nitrile on the basis of the screening of a large amount of toxicities and field controling test
After diafenthiuron compounding, there is obvious synergistic effect to various crop pests, the present invention completed after further research,
The relevant report on second azoles mite nitrile and diafenthiuron are compounded is there is no at present.
The content of the invention
The invention aims to solve the deficiencies in the prior art, there is provided a kind of miticidal effect is good, evil mite resistance is low, property
The agricultural insecticide composition of matter stabilization, the Pesticidal combination active component includes second azoles mite nitrile and diafenthiuron, the desinsection group
Compound compounding has obvious synergistic effect.
Application another object of the present invention is to provide the Pesticidal combination, the Pesticidal combination is widely used in
The insect pests such as preventing and treating citrus red mite, European red mite, apple Tetranychus urticae, cotton red spider.
To achieve these goals, the present invention adopts the following technical scheme that scheme：
A kind of Pesticidal combination, its main active is second azoles mite nitrile and diafenthiuron, wherein, second azoles mite nitrile and diafenthiuron
Weight ratio is 1:20-20:1, preferably 1:10-5：1.
Further, the weight percentage of active component is 1-90%, preferably 8-60% in the Pesticidal combination.
Further, composition pesticide of the invention can be aided with auxiliary element conventional during the formulations of pesticide are processed and be prepared into
It is adapted to any one formulation for agriculturally using, including it is wettable powder, water dispersible granules, aqueous emulsion, microemulsion, missible oil, outstanding
Floating agent, suspension emulsion.
Further, described agricultural chemicals auxiliary element includes dispersant, wetting agent, emulsifying agent, antifreezing agent, defoamer, increasing
Thick dose, stabilizer, disintegrant, film forming agent, colouring agent, filler and solvent.
Further, the compound that composition pesticide of the invention can have desinsection, weeding, bactericidal property with other is mixed
Conjunction is used, also can be mixed with nematicide, fertilizer, plant growth regulator, nutrient for plants, soil conditioner or biostimulant
Conjunction is used.
The frequency of administration and usage amount of the present composition change and small variations with crops, insect, weather condition,
The purpose of effective preventing and treating can be reached by using appropriate dosage.
Each material is blended during Pesticidal combination of the invention can be directly prepared into finished product preparation form, i.e. composition,
It is directly used in mite killing；The composition of composition can also be provided by independent preparation, using preceding in bucket（Tank）In directly mix.The present invention
Concentrate the concentration of the active material is generally mixed to get with water.
Compared with prior art, agricultural insecticide composition of the invention has the beneficial effect that：（1）Insecticidal combinations of the invention
Active component second azoles mite nitrile and diafenthiuron are compounded in certain scope in thing, and the preventing and treating to various crop insect pest has significantly
Synergistic function, can reduce pesticide activity component usage amount, improve prevention effect；（2）In Pesticidal combination of the invention
The active component mechanism of action is different, and both can overcome and/or delay the drug-fast generation of pathogen compounding；（3）This hair
Bright Pesticidal combination is to crop safety, and environmental pollution is small.
