Abstract
The invention relates a high-efficiency pesticide composition used for killing agricultural pests. The high-efficiency pesticide composition is composed of the components of, by weigh, 10-40 parts of bifenthrin, 10-50 parts of flubendiamide, 20-40 parts of dinotefuran and 20-40 parts of spinetoram. The pesticide composition provided by the invention has a significant synergistic effect, such that a pesticidal spectrum is broad, effective component doses can be effectively reduced, and application cost can be reduced; with the pesticide, pest drug resistance can be retarded, and environmental pollution and pesticide residue can be effectively reduced. The pesticide causes no phytotoxicity, and has low toxicity and no chronic toxicity to human and mammals. The pesticide has significant effects against paddy rice stem borers and leaf rollers, and homoptera piercing-sucking mouthpart pests which are mainly plant hoppers, aphids and mites.
Description
Technical field
The present invention relates to the field of pesticides for agricultural insect pests control, particularly a kind of efficient pesticides containing Biphenthrin, fipronil bisamide, MTI-446 and ethyl pleocidin.
Background technology
Insecticide residues and the toxicity problem to animal in agricultural product are the focuses that people pay close attention to always.
Biphenthrin:

Molecular weight: 845.7356
Structural formula:
Biphenthrin is very high to fish toxicity, is 0.00015mg/L to rainbow trout LC50 (96 hours), water flea LC50 (48 hours) 0.00016mg/L.But because this medicament has very high affinity interaction in soil, and it is water-soluble low again, therefore actual influence is less.This agent is medium to honeybee toxicity, to the high poison of silkworm.Insecticidal activity is very high, is mainly and tags and stomach poison function, without interior suction and fumigation activity.Rapidly, the lasting period is long, and insecticidal spectrum is wide in its effect.
Biphenthrin is a kind of efficient pyrethroid Insecticidal and acaricidal agent.Have tag, stomach poison function, without interior suction, fumigation action.Insecticidal spectrum is wide, also has favorable effect to mite.Effect rapidly.Do not move in soil, safer to environment, the longevity of residure is long.
Applicable crops has banana, barley, cotton, lettuce, tea, apple, wheat, tomato, pea, beanpod, white lupin, clover, green soya bean, pears, sugarcane, dry red pepper, muskmelon, potato, verdant, Chinese cabbage, red pepper, mango, eggplant, cauliflower, grape, peanut, watermelon, tobacco, corn, cocoa, asparagus, shallot.Each Species of Lepidopterous Larvae, aleyrodid, aphid, phytophagy tetranychid can be prevented and treated.
Using method (1) aleyrodid at aleyrodid initial stage of origination, (about 2/strain) dispenser when insect density is low.With 2.5% Uranus missible oil 2000-2500 times of liquid, spraying.2.5% Uranus missible oil, 4000 times of liquid and 25% buprofezin wetting powder 1500 times of liquid can be selected when insect pest situation is serious mixed.(2) aphid is in initial stage of origination 2.5% Uranus missible oil 2500-3000 times of liquid, spraying, about the 15 days longevity of residure.Same dose also can prevent and treat multiple defoliator.(3) if two spotted spider mite is in one-tenth mite emergence period dispenser.With 2.5% Uranus missible oil, 2000 times of liquid, spraying, can effectively control them in 10 days and cause harm.
Fipronil bisamide:

Structural formula:
Toxicity: MTI-446 is fool proof to mammal, its acute oral LD50 is male rat 2450mg/kg, female rats 2275mg/kg; Male mice 2840mg/kg, female mice 2000mg/kg.To rat acute through skin LD50>2000mg/kg (female, male).Without teratogenesis, carcinogenic and mutagenicity.MTI-446 is also fool proof to aquatile.Ichthyotoxin test show, MTI-446 to carp nm (48h) >1000mg/L, to water flea >1000mg/L.Equally, MTI-446 is also very low to birds toxicity, to quail acute oral LD50>1000mg/kg.Through learning honeybee test, MTI-446 to honeybee safety, and does not affect honeybee producting honey.
This medicament has the features such as tag, strong, the quick-acting height of absorption in stomach toxicity and root, long 3-4 week lasting period (theoretical lasting effect 43 days), insecticidal spectrum are wide, and have excellent preventive effect to sucking insect, and namely show very high insecticidal activity at very low dosage.Be mainly used in the aphid in the various crop such as control wheat, paddy rice, cotton, vegetables, fruit tree, tobacco leaf, leafhopper, plant hopper, thrips, aleyrodid and resistant strain thereof, have efficiently coleoptera, diptera and Lepidoptera, diptera, beetle order and total wing order insect simultaneously, and to blattaria, have efficiently from the sanitary insect pest such as ant, housefly.It was introduced in 1993 in Japan, had been that the countries in Asia of representative, this country and European Countries obtain and register with Korea S later.
The insecticidal spectrum of MTI-446:
Rice grub
Efficient: brown planthopper, white-backed planthopper, small brown rice planthopper, rice leafhopper, rice spider rafter stinkbug, star stinkbug, green rice bug resemble, red must fleahopper, the negative mixed worm of rice, rice cylinder water snout moth's larva.
