Problems solved by technology

If the azadirachtin aqueous solution for treating root-knot nematodes and the azadirachtin aqueous solution for treating fruit tree root cancer are directly used to treat leek root maggots, a better control effect cannot be achieved, and the effect is not obvious
In addition, the existing azadirachtin aqueous solution for the treatment of root-knot nematodes and the azadirachtin for the treatment of fruit tree root cancer are aqueous solutions
Not suitable for direct spraying as a pesticide

Abstract

The invention discloses a pesticide and in particular relates to an azadirachtin water aqua for treating Chinese chive root maggot and a preparation method thereof. The azadirachtin water aqua for treating Chinese chive root maggot is prepared from such raw materials in parts by weight as 0.0045-0.005 part of azadirachtin A, 0.008-0.12 part of azadirachtin B, 0.24-0.25 part of neem stock extract F, 0.14-0.16 part of neem leave extract G and 0.48-0.52 part of water. The azadirachtin water aqua is high in pest killing efficiency, capable of improving soil, easily degradable, residue-free, free from drug resistance, good in stability and suitable for direct injection.

Description

technical field [0001] The invention relates to a pesticide, in particular to an azadirachtin aqueous agent for treating leek root maggots and a preparation method thereof. Background technique [0002] Chive maggot, scientific name Chive tardigrade ( Bradysia odoriphaga Yang Yang et Zhang), belonging to Diptera, Longocera, Oculomidae, Bradyophthalidae, is a unique pest species in my country, and there is no relevant report abroad so far. Adult males of chive maggots are 3.3-4.8 (average 4.3) mm long and dark brown; females are 4-5 (average 4.6) mm long. The general characteristics are similar to those of males, but the antennae are shorter and thinner. Adults do not feed, prefer humus, have phototaxis, but prefer to move in damp and weak light environments. It is most active at 9-11 in the morning, and it is also the peak of copulation, and it is not active at night. Females tend to lay eggs in hidden places near the host, mostly in soil crevices, gaps between plant b...
