Abstract
The invention belongs to the technical field of agricultural insecticides, and particularly relates to a Clothianidin/Diafenthiuron compound insecticidal composition. The effective ingredients are Clothianidin and Diafenthiuron in a weight ratio of 1:(4-7), preferably 1:(5-6). The Clothianidin/Diafenthiuron compound insecticidal composition is composed of the effective ingredients with different action mechanisms, so that the action sites are increased, thereby being beneficial to overcoming and postponing the generation of insecticide resistance of insects, and widening the insecticidal spectrum; and the invention greatly enhances the insecticidal effect, has the advantages of long preventive effect time and lower consumption of effective ingredients in the field, lowers the production and use cost, and reduces the insecticide residue and environmental pollution.
Description
Technical field
The invention belongs to the agricultural fungicides technical field, particularly a kind of clothianidin and diafenthiuron complex insecticidal composition.
Background technology
Clothianidin is a kind of insecticide in anabasine, is the novel pesticide of highly effective and safe, high selectivity, and its effect is similar with nAChR, have tag, stomach toxicity and systemic activity.Be mainly used on paddy rice, vegetables, fruit tree and other crops anti-ly eliminating aphis, the insecticide of Semiptera, coleoptera, diptera and some Lepidoptera class pest such as leafhopper, thrips, plant hopper, have efficient, wide spectrum, consumption is few, toxicity is low, the drug effect lasting period long, to crop without poisoning, use safety, with conventional pesticide without advantages such as cross resistances, remarkable interior suction and osmosis are arranged, and are the another new varieties that substitute high malicious organophosphorous pesticide.Its novel structure, special, performance is compared more excellent with traditional nicotinic insecticide, and large-scale insecticide variety might become international.
Diafenthiuron is a kind of novel Thiourea efficient insecticide, miticide, have tag, stomach toxicity, interior suction and fumigation action, and have certain ovicidal effect, low toxicity, but to fish, the high poison of honeybee.Change the material with insecticidal activity under ultraviolet light, have stronger activity to having produced serious drug-fast insect on vegetables.Can prevent and treat aphid, aleyrodid, leafhopper, noctuidae pests and evil mite on various crop and ornamental plants.Mainly be made into medicine liquid spray with wetting powder and use, control vegetables diamond-back moth, cabbage caterpillar and cotton red spider, general mu active ingredient 20～30 grams, 10～15 days lasting periods.
Often there is defective in various degree in the insecticide variety that contains the single-activity component in the Agriculture Field Pests control, easily develop immunity to drugs as the dosage major pest, and desinsection narrow range, application times are added heavily environmental pollution etc.For the upper insect that produces resistance of control agricultural, a kind of way is to release new and the new component of existing kind without cross resistance.But the development cost of new active ingredient is high, and the construction cycle is long, and does not all catch up with the speed that insect produces resistance forever.Other way in the process of practical operation, is difficult to really play obvious effect such as crop allocation adjustment, different agricultural chemicals rotations etc.
Summary of the invention
For addressing the above problem, the invention provides that a kind of insecticidal spectrum is wide, cost is low, have the complex insecticidal composition of synergistic effect.
Technical scheme of the present invention is: a kind of clothianidin and diafenthiuron complex insecticidal composition, its active ingredient are clothianidin and diafenthiuron.
The weight ratio of described active ingredient clothianidin and diafenthiuron is 1:4～7, preferred 1:5～6.
Above-mentioned active ingredient clothianidin and diafenthiuron are all insecticides well known in the art, can buy by various commercial channel.
Needs according to using add the auxiliary materials commonly used such as pesticide field surfactant, carrier, antifreezing agent, thickener or disintegrant, composition can be made wetting powder or water dispersible granules or aqueous suspension agent.
Clothianidin of the present invention and diafenthiuron complex insecticidal composition, can be used for preventing and treating aphid on fruit tree egger, vegetables, leafhopper, plant hopper, aleyrodid, mite class etc., drug effect increases substantially, the field consumption of active ingredient reduces, reduce costs, reduce pollution, reduction pest resistance to insecticide, the purpose that extends the preventive effect time thereby reach.
Beneficial effect of the present invention is:
1, the present invention is comprised of the active ingredient of different mechanism of action, and action site increases, and is conducive to overcome and delays the drug-fast generation of insect pest, and having widened insecticidal spectrum;
2, drug effect of the present invention increases substantially, and the preventive effect time is long, and the field consumption of active ingredient descends, and has reduced production and use cost, reduces residue of pesticide and environmental pollution.
Embodiment
Illustrate the present invention below in conjunction with embodiment.
At first adopt the composite rear co-toxicity biologicall test of clothianidin and diafenthiuron to test to prove that both strengthen composite rear drug effect.
One, test method
Clothianidin, diafenthiuron are become series concentration with acetone diluted, standby.Virulence test adopts the stomach toxicity experimental method.Gather fresh cabbage leaves and make leaf dish (d=1.6cm) with card punch, immerse the good liquid 5S of dilution, put into the culture dish (paving same diameter filter paper) of R=9cm, under 25 ℃ of conditions the hungry 4h of access 2～3 age cabbage caterpillar, 20 of every processing, every concentration repeats 3 times, establishes blank.Put in illumination box (25 ± 2 ℃, RH=75%, L:D=14:10).Check dead borer population in 24h, 48h, 72h, 96h.Touch polypide with writing brush, larva is motionless is death.
Two, data survey and statistical analysis
Adopt the abundant co-toxicity coefficient method representation of Sun Yun: experimental data is analyzed with probability value analytical method, with Abbott formula correction lethality, after being converted into percent concentration, extension rate carries out again logarithm conversion, corrected mortality is done the probit value conversion and is obtained virulence regression equation Y=a+bx, then obtains LC50 according to virulence regression equation.Calculate actual toxicity index and the theoretical toxicity index of mixture, and obtain the co-toxicity coefficient CTC of mixture, according to the synergistic effect that co-toxicity coefficient CTC estimates mixture, determine best proportioning.Computing formula is as follows:
The ratio of toxicity index * B in mixture of the ratio+B of toxicity index * A in mixture of the theoretical numerical value=A of the toxicity index of mixture.
According to the symphyogenetic co-toxicity coefficient criteria for classifying of mixed insecticide: co-toxicity coefficient (CTC) 〉=100 shows as synergistic effect; CTC≤80 show as antagonism; 80＜CTC＜100 show as summation action.
Result of the test is as shown in table 1:
The co-toxicity coefficient of table 1 clothianidin and the composite mixture of diafenthiuron
