Abstract
The invention provides an insecticidal composition capable of high-precisely and efficiently controlling homoptera pests. The insecticidal composition comprises one or two insecticides and one sex pheromone of homoptera pests. Through the synergetic effect between sex pheromone and insecticides, the pests can be precisely killed, the waste of insecticide is reduced during the using process, the utilization rate of insecticide is improved, the cost of insecticide for farmers is reduced, the service life of chemical pesticide is prolonged, and the resistance of pests to pesticide is weakened.
Description
Technical field
The present invention relates to a kind of method improving agricultural chemicals bioavailability, more specifically, the present invention relates to the Pesticidal combination containing one or more insecticides and homoptera pest sex pheromone, for improving the availability of agricultural chemicals.
Background technology
Start chemical pesticide as far back as the 1950's to use on a large scale on crops, drastically increase the output of crops, promote developing rapidly of agricultural.In control of agricultural pest, chemical pesticide has the features such as instant effect, effective, drug cost is low, dark liking by wide farmers, up to now, chemical pesticide medication occupies very large ratio, and about 95%, be topmost means and measure in China's pest management.In recent years, due to single drug or not Scientific Usage of Drugs, caused the agricultural chemicals of many damage by disease and insect to current use to create resistance, become a great problem of chemical control.Meanwhile, a large amount of pest natural enemy is also killed, heavy damage agricultural ecological balance and bio-diversity.More allow people worry, domestic equipment for plant protection falls behind, and adds that using method is improper; Pesticidal products formulation falls behind; can not evenly dispenser, cause agricultural chemicals availability extremely low, data shows; 2005; the Pesticide use amount more than 220,000 tons of China whole year, agricultural chemicals only has the agricultural chemicals of about 30% to be used effectively, and the agricultural chemicals of about 70% does not only play the effect of pest control; add the drug cost of peasant, also severe contamination is caused to ecotope.
According to relevant expert's initial estimate, if pesticide efficacy is brought up to 50%, promote 20 percentage points, only at minimizing cost, this just can be increased farmers' income more than 10,000,000,000 yuan.Be close on during the decade from 2005 to 2013, the main Pesticidal products of China completes update substantially, and active ingredient mu consumption drops to tens grams even several grams from a few hectogram; New and effective accurate plant protection apparatus obtains large-scale application.The scientific and technological quality of dispenser theme crowd is greatly improved, and the specialized Unifying control of damage by disease and insect advances fast, but pesticide efficacy is still solid to be walked not, and rest on about 30%, the agricultural chemicals of 70% is lost to soil, water source or floats in environment.In human industry's development of civilization this stage to today, especially in the present stage of China, the destruction of environment has had a strong impact on the progress of human lives, Environment control, promotes a conservation culture extremely urgent.Therefore, reasonable efficiency utilization chemical pesticide becomes when a previous difficult problem in the urgent need to address.
Summary of the invention

The present invention, by adding insect sex pheromone in insecticide, makes this Pesticidal combination obtain more superior insecticidal properties.Compared with the insecticide that use is single, due to the insect sex pheromone increased in the present composition can induce insect initiatively, go to each insecticide to split a little accurately, insect is contacted indirectly or directly, eats insecticide and dead by mistake, thus the probability making insecticide hit target pest promotes greatly.Meanwhile, the dosage of each aerosol bomb reduces greatly, per season crops insecticide times for spraying, food-safety problem improves; Compared with the insect sex pheromone that use is single, because the present composition includes insecticide, can kill target pest rapidly, accurately, avoid insect shake off collector and escape, the cycle that takes effect is shorter, desinsection is more thorough, improve agricultural output thus, reduce loss and the drug cost of peasant household, in addition, also can exempt and be difficult to biodegradable trapper because using and lure core, cause serious environmental pollution.
Embodiment
The good insecticidal of active agent combinations of the present invention can be seen from following examples.Independent use insect sex pheromone shows that onset is slow, it is low that independent use of insecticide shows utilization ratio of drug, but the quick-acting of active agent combinations of the present invention is fast, and activity exceeded active simply adding and.
According to theory death value (%) of the given present composition of following Colby formulae discovery.When preventing and treating percentile numerical value higher than the percentile theoretical value of control, think that the present composition obtains potentiating pesticidal active.Colby computing formula is as follows:
E=X+y-(X × Y)/100, wherein
