Description

Insecticidal composition containing pirimicarb and dicyclaniliprole and application thereof
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to an insecticidal composition containing pirimicarb and diproprionate and application thereof.
Background
The pirimicarb is a widely used carbamate pesticide, which kills pests by inhibiting the acetylcholinesterase of insects and influencing the normal nerve conduction of the insects, mainly prevents and treats dipteran pests, has special effect on aphids and other piercing-sucking mouthpart pests, but basically has no effect on cotton aphids, can be used for fruit trees, cereals, berry fruits, beans, cabbages, rapes, lettuce, beet, potatoes, flowers and some ornamental plants, and has the characteristics of high efficiency, quick acting and strong selectivity.
The dicyclopropyl tetramine is a brand new biological source pesticide. Different from the action mechanism of the conventional insecticide, the dicyclopropyl tetramine causes the insects to deaf, lose coordination and direction feeling, further cannot take food, lose water and finally die due to hunger by interfering the function of the chord organ of the insects. The insecticidal composition is mainly used for preventing and treating piercing-sucking and sucking mouthpart pests, such as aphids, whiteflies, psyllids, scale insects, mealybugs, leafhoppers and the like, is suitable for economic crops, field crops, ornamental plants and the like, and has the characteristics of quick response, high efficiency, broad spectrum, long lasting period and the like.
The pirimicarb has high control effect, low dosage and low cost, has no adverse effect on natural enemies of aphids such as ladybug, aphidfly, aphidiidae and the like, and is a pesticide recommended to be used in the production of grade-A green food in China. But the pesticide is used as a special aphicide for a long time, has short duration and is easy to cause pests to generate drug resistance. In order to delay the drug resistance of pests to pirimicarb and prolong the drug-holding capacity of the pesticide, the research and development of the compound pesticide of pirimicarb have important significance. On the basis of indoor screening and field experiments, the pirimicarb and the dicyclaniliprole are screened out unexpectedly for compounding, so that the synergistic effect is obvious, and no relevant report about compounding of the pirimicarb and the dicyclaniliprole is found in the existing literature.
