Description
Technical field
The invention belongs to agriculture insect prevention field, and in particular to be a kind of to include double third ring worm esters and bistrifluron
Pesticidal combination and its application for preventing and treating crop pests.
Background technology
Aphid, also known as aphid, aphid etc., belong to Homoptera Aphidiadae, are sucking pest, and Chang Qunju is in blade, tender
The positions such as stem, bud, bud top, thorn inhales juice, makes leaf-shrinkage, curling, deformity, causes die back even whole strain dead when serious
Die.The honeydew of aphid secretion can also induce sooty mould, virosis and cause ant infestations etc., and aphid has brevicoryne brassicae, black peach aphid, cotten aphid
Etc. a variety of, the various crops such as grain, cotton, oil, fruit tree, vegetables can be endangered.Aphid to the nicotinoids such as pymetrozine, Diacloden medicament
Very big resistance is generated, causes dosage to continue to increase, times for spraying showed increased.
Double third ring worm esters, English name is afidopyropen, is that Japanese Meiji Pharmaceutial Ltd. and Japanese North are ground
A kind of novel pesticide of institute's joint development is studied carefully, with brand-new mechanism of action, to sucking pest such as aphid, plant hopper, shell
Worm and leafhopper are respectively provided with good lethal effect, available for vegetables, fruit tree, imtertilled crop and ornamental plant etc., either blade face
Processing, plantation processing or soil treatment all have good effect, and toxicity is very low.
Bistrifluron, is the benzoyl urea high activity insect growth regulator, IGR reported by Dong Bao chemical companies of South Korea, category
It is double in the chloro- 3,5- of new 2-（Trifluoromethyl）Phenylbenzoyl urea derivative, structure is novel, and mechanism of action is unique and biological living
Property it is high.Bistrifluron has significant Growth inhibition to insect, has special efficacy to trialeurodes vaporariorum, and the compound can press down
The synthesis of insect chitin processed, influence endepidermis generation, prevents insect dead from smoothly casting off a skin, can effectively prevent and treat vegetables, tea
Most Lepidopteras of the various crops such as leaf, fruit tree, cereal, paddy rice, homoptera pest, can also prevent and treat termite.
In agriculture actual application, long-term a large amount of chemical insecticides for using single kind are easily caused the anti-medicine of insect
The generation of property, so as to influence the service life of pesticide species.By the agricultural insecticide active component of the different mechanisms of action, different cultivars
Carrying out compounding has the advantages that delaying drug resistance, improves prevention effect, particularly after some active insecticidal components compounding, it is also possible to have
There is synergistic function, so as to reach the usage amount for reducing pesticide active ingredient, further reduce pollution and people to environment
The threat of health.At present, it there is no and be related to the relevant report that double third ring worm esters and bistrifluron are compounded.
