Abstract

The invention discloses a method for preventing and controlling Orah (late-maturing hybrid citrus) phyllocnistis citrella. In an early stage of phyllocnistis citrella pest damage, a bisultap solutionis sprayed, in a stage of phyllocnistis citrella pest damage, a plant source pesticide is sprayed, wherein the plant source pesticide comprises the following raw materials: incised corydalis herbs, ailanthus altissima, achyranthis radix, anabasis aphylla branches, Illicium verum fruits, fennel and black falsehellebore. According to the invention, the raw materials of the plant source pesticide aresimple, the quality is stable, the practical prevention and control effects can be obviously improved, the use amount of the pesticide is reduced, the duration time of the pesticide control effect isprolonged, pests do not generate pesticide resistance, and therefore effects of saving work, time and labor are achieved.

Description

technical field

[0001] The invention relates to the field of agricultural planting, in particular to a method for controlling the citrus leaf miner. Background technique

[0002] Leafminer moth, the larvae damage the young shoots and leaves of the citrus citrus, sneak under the epidermis to feed on the mesophyll, lift the epidermis, and form a silver-white curved tunnel. Insect feces are left inside, forming a black line in the center. Due to the twists and turns of the insect passage, the new leaves are curled, hardened, and the leaves fall off. The kill rate of autumn shoots is 100%. Due to the large number of wounds, it often induces the occurrence of canker, and provides a good wintering place for pest mites, shield scales, mealybugs and leaf rollers.

[0003] Traditional control methods mostly use chemically synthesized insecticides, which pollute the environment and easily cause insecticide resistance.

[0004] The disclosure of the above background technical conten...
