Method and preventing and treating macrosiphoniella sauborni

Abstract

The invention discloses a method for preventing and treating macrosiphoniella sauborni. The method comprises the following steps of uniformly stirring 10-50 parts of plant ash, 10-50 parts of lime and200-1000 parts of soil; adding 1-2 parts of octyl mercaptan, 2-5 parts of chilli powder and 1-2 parts of 2,5-dihydroxy-benzoic acid, 1-5 parts of (E)-N-(6-chloro-3-picolyl)-N-ethyl-N'-methyl-2-nitroethylenediamine, 1-5 parts of N-(N-cyano-ethylimino)-N-methyl-2-chloropyridine-5-methylamine, 1-2 parts of pyriproxyfen, 10-50 parts of an organic solvent and 20-50 parts of water, mixing with water, and stirring with stood soil; controlling the environment temperature at 20-25 DEG C, and controlling the relative humidity at 50%-60% until chrysanthemum germinates; placing a pest luring device at the position 10-20cm away from a flower pot when the chrysanthemum grows to 10-15cm. the treatment is carried out in the chrysanthemum cultivation soil, worm eggs in the soil can be directly killed, themacrosiphoniella sauborni can be lured through the pest luring device in the later period to avoid damage to the chrysanthemum, no pesticide is applied in the whole growth period of the chrysanthemum, the macrosiphoniella sauborni can be efficiently killed, no pesticide residues exist on the chrysanthemum, and the method is green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of aphid prevention and control, in particular to a method for preventing and treating the aphid chrysanthemum. Background technique [0002] Chrysanthemum is three of China's top ten famous flowers, one of four gentlemen (plum blossom, orchid, bamboo and chrysanthemum) in flowers, and one of four cut flowers in the world (chrysanthemum, Chinese rose, carnation, gladiolus). , aphids have a great impact on the quality of chrysanthemums, among which the chrysanthemum aphid is the most harmful. [0003] Chrysanthemum chrysanthemum sucks juice on the leaves and stems of host chrysanthemums. When chrysanthemums germinate and germinate leaves in spring, they can also cluster to damage new buds and new leaves, making it difficult for new leaves to unfold, and the elongation and development of stems are affected; When damaging Atractylodes macrocephala, the leaves turn yellow, the plants shrink, the growth is poor...
