Embodiment 1

[0028] A method for preventing and controlling Leafminer of Citrus citrus: Spraying 30% insecticidal double water agent 500-800 times liquid in the early stage of Leafminer infestation, spraying botanical insecticides in the infestation period of Leafminer, and also needing to spray Cichlid japonicus Cut into 5cm sections, sprinkle in the middle of the citrus trees, and apply 200kg per mu;

[0029] The plant-derived insecticides are in parts by weight, and include the following raw materials: 10 parts of Ailanthus japonica, 2 parts of Ailanthus chinensis, 2 parts of Achyranthes bidentata, 5 parts of leafless horsetail, 1 part of star anise, 1 part of fennel, 10 parts of hellebore;

[0030] The preparation method of botanical insecticide comprises the following steps:

[0031] S1: Grind Ailanthus japonicus, Ailanthus sinensis, Achyranthes bidentata, horsetail, star anise, fennel, and hellebore into a size that passes through a 5-mesh sieve;

[0032] S2: Extract the crushed ra...

[0037] A method for preventing and controlling Leaf Miner of Citrus citrus: Spraying 30% insecticidal double water agent 800 times liquid at the early stage of Leaf Miner infestation, spraying botanical insecticide during the Leaf Miner infestation period, and cutting the chrysanthemum japonicus into pieces Scatter 15cm in the middle of the citrus trees, 300kg per mu;

[0038] The botanical insecticide includes the following raw materials in parts by weight: 100 parts of Ailanthus japonicus, 10 parts of Ailanthus sinensis, 8 parts of Achyranthes bidentata, 15 parts of leafless horsetail, 9 parts of star anise, 9 parts of fennel, 20 parts of hellebore;

[0039] The preparation method of botanical insecticide comprises the following steps:

[0040] S1: Grind Ailanthus japonicus, Ailanthus sinensis, Achyranthes bidentata, horsetail, star anise, fennel, and hellebore into a size that passes through a 10-mesh sieve;

[0041] S2: Extract the crushed raw material in step S1 with 3 ...

Embodiment 3

[0046] A method for preventing and controlling Leaf Miner of Citrus citrus: Spray 30% insecticidal double water agent 600 times liquid in the early stage of Leaf Miner infestation, spray botanical insecticide in the infestation period of Leaf Miner Scatter in the middle of the citrus trees in 8cm sections, 220kg per mu;

[0047] The botanical insecticide includes the following raw materials in parts by weight: 30 parts of Ailanthus japonicus, 4 parts of Ailanthus sinensis, 3 parts of Achyranthes bidentata, 8 parts of leafless horsetail, 3 parts of star anise, 3 parts of fennel, 13 parts of hellebore;

[0048] The preparation method of botanical insecticide comprises the following steps:

[0049] S1: Grind Ailanthus japonicus, Ailanthus sinensis, Achyranthes bidentata, horsetail, star anise, fennel, and hellebore into a size that passes through a 5-mesh sieve;

[0050] S2: Extract the crushed raw material in step S1 with 3 times of water, and filter to obtain extract A and fi...

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...
