Description
[technical field]
The present invention relates to a kind of Pesticidal combination, it contains emamection benaoate and nimbin as active component.
[background technology]
Crops all need to use a large amount of agricultural chemicals for this reason and carry out the extermination of disease and insect pest to retrieve crop yield loss because damage by disease and insect causes crop yield loss to estimate every year.In recent years, for example the harm on paddy rice, fruit tree, vegetables, flowers and the diversified economy crop is more and more serious crops in insect pest, and because the agricultural chemicals abuse makes the insect resistance more and more serious to the generation of agricultural chemicals, causes pest controling effect to reduce year by year.The pesticide species that therefore, still just need have better pest controling effect.
Emamection benaoate (emamectin benzoate) is a kind of new and effective semisynthetic antibiotics class insecticidal/acaricidal agent that begins to synthesize from fermented product Avermectin B1, and it has the characteristics of super-high-efficient, low toxicity, noresidue, biopesticide such as nuisanceless.Larva and other many insects to lepidopterous insects do harm to the active high of mites, existing stomach poison function has action of contace poison again, under low-down dosage, has good effect, and in the process of pest control, arthropods is not injured, enlarged insecticidal spectrum in addition, reduced toxicity people and animals.
Nimbin (azadirachtin) is a kind of biological insecticides that extract in seal chinaberry seed, can prevent and treat and plant farming, woods, storage and sanitary insect pest more 200, be universally acknowledged wide spectrum, efficient, low toxicity, easily degrade, the insecticide of noresidue.
