Abstract
The invention relates to an efficient insecticide containing a biopesticide lepimectin, chlorpyrifos and spirotetramat. The insecticide is composed of the following components in parts by weight: 20-60 parts of the biopesticide lepimectin, 10-30 parts of chlorpyrifos and 35-55 parts of spirotetramat. The insecticidal composition provided by the invention has an obvious synergic effect and is safe and harmless to human, livestock, crops and natural environment, resistance to pesticides is hard to generated for injurious insects, and the insecticidal composition has a remarkable killing effect on injurious insects such as plutella xylostella, beet armyworms, cotton bollworms, striped rice borers, mealybugs, homoptera piercing-sucking mouthparts which are mainly planthoppers, aphids, brown planthoppers and the like. Meanwhile, the efficient insecticide further can reduce the damages on the environment.
Description
Technical field
The present invention relates to the field of pesticides for agricultural insect pests control, particularly a kind of efficient pesticides containing biopesticide lepimectin, chlorine pyrazothion and spiral shell worm ethyl ester.
Background technology
Insecticide residues and the toxicity problem to animal in agricultural product are the focuses that people pay close attention to always.
Biopesticide lepimectin:
Physicochemical property: a kind of 16 membered macrolide antibiotic, are made up of derivative L .A3 and L.A4 of milbemycinA3/A4, wherein L.A3≤20%, L.A4 >=80%.Its CA accession number is respectively: 171249-10-8 (L.A3) and 171249-05-1 (L.A4).
Biopesticide lepimectin is the derivative being total to mibemycin (milbemycin) A3/A4 that company finds by Japan three, uses in 2006 in Japan's registration.Lepimectin is as the activator of glutamic acid, the open frequency of GluCl-can be increased, thus cause film to increase C1-permeability, cause the hyperpolarization of neuron resting potential, make it be difficult to depolarising, nerve conduction is obstructed, thus cause the flaccid paralysis of insect body wall muscle, block the wriggling of insect pharyngeal muscle, cause ingestion difficulty and cause death.
Vegetables and the fruit such as wild cabbage, tomato, oranges and tangerines, strawberry and grape is used for, main insect such as control Lepidoptera and Homoptera etc. as novel pesticide.This medical instrument has insecticidal activity high, and dosage is few, to person poultry safety, free from environmental pollution, and selectivity is strong, does not injure natural enemy, also not easily produces the features such as resistance, can use with avermectins rotation, in case Avermectin produces resistance.Therefore it is called as one of the most promising wide spectrum, efficient, the novel insecticide without cross resistance at present.
Chlorine pyrazothion:
Chinese another name: O, O-diethyl-O-(3,5,6-trichloro-2-pyridyl) thiophosphate
English name: chlorpyrifos (ANSI, ISO, BSI)
Molecular formula: C
9h
11cl

Molecular weight: 350.5
Structural formula:
Toxicity: belong to moderate toxicity insecticide.Former medicine rat acute LD50 of passing through mouth is 163mg/kg, acute through skin LD50>2g/kg; Have slight stimulation to experimental animal eyes, have obvious stimulation to skin, long-time multiple-contact can produce and burn.The sub-anxious per os action-less dose of rat is 0.03mg/kg, and chronic per os action-less dose is 0.1mg/kg.The chronic per os action-less dose of dog is 0.03mg/kg.Teratogenesis, mutagenesis, carcinogenesis is had no under test dose.In room air, maximum permissible concentration is (TLV) 0.2mg/m.To fish and aquatic toxicity higher, trout LC50 is 15mg/L (96 hours, 72 DEG C), poisonous to honeybee.Chlopyrifos 40.7% missible oil, rat acute LD50 of passing through mouth is 590mg/kg, exempt from acute through skin LD50 be 2330mg/kg, irritant to skin, eyes.Kill the impatient LD50 of passing through mouth >2g/kg of the blue pearl 14% granule rat of worm, acute through skin >2g/kg, Acute inhalation LC50>0.007 μ g/L (7 hours), irritant to eyes, skin.
Formulation: 40.7% missible oil, 14% granule.
Chlopyrifos is a kind of efficient, broad-spectrum organophosphorous pesticide, have insect tag, stomach toxicity and fumigation action, especially have extraordinary effect to the control of brown planthopper.
Spiral shell worm ethyl ester is tetronic acid compounds, belongs to similar compound with insecticidal/acaricidal agent spiral shell mite ester (spirodiclofen) of Bayer company and Spiromesifen (spiromesifen).Spiral shell worm ethyl ester has unique function Characteristics, is one of modern pesticides so far with two-way Uptake and translocation performance.This compound upwards can move down in whole plant corpus, arrives at blade face and bark, thus control is as on romaine lettuce and Chinese cabbage internal lobe, and the corticole insect of fruit.The interior absorption of this uniqueness can protect newborn stem, leaf and root, prevents ovum and the larval growth of insect.Its another feature is that the lasting period is long, can provide the effective control reaching 8 weeks.
Spiral shell worm ethyl ester high-efficiency broad spectrum, can effectively prevent and treat various sucking pest, as aphid, thrips, wood louse, mealybug, aleyrodid and scale insect etc.Applicable chief crop comprises, cotton, soybean, oranges and tangerines, tropical fruit tree, nut, grape, lupulus, potato and vegetables etc.Research shows it to important beneficial insect as ladybug, syrphus fly and parasitic wasp have good selectivity.
