Abstract

The invention discloses a twig growth controlling bactericide composition for citrus. The twig growth controlling bactericide composition is prepared by the following raw materials in parts by weight:0.2-10 parts of garlic, 0.2-10 parts of fresh ginger, 2-20 parts of pink, 2-40 parts of eucalyptus leaves, 40-300 parts of lonicera hypoglauca miq leaves, 0.2-30 parts of herba portulacae, and 0.01-0.7 parts of mepiquat chloride. Active ingredients prepared by the above raw materials are mixed with auxiliary materials, so wettable powder or water dispersible granules are prepared, and can be usedfor preventing and treating citrus canker, anthracnose, penicilliosis and green mold. In spring and summer in which diseases frequently occur, the composition is capable of preventing and treating the diseases, and the mepiquat chloride in the active ingredients is capable of inhibiting growth of spring twigs and summer twigs of the citrus, and achieving the effect of chemically controlling the twigs and promoting flowers and protecting fruits. The twig growth controlling bactericide has the characteristics of less dosage, high pesticide effect, quick effect, and no residue, and can be conveniently and safely used. The twig growth controlling bactericide composition has the effects of stabilizing production and increasing production while applied to citrus production.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a citrus shoot-control fungicide composition and a preparation method thereof. Background technique [0002] Citrus canker is a worldwide disease, which originated in Asia and is most common in Asian countries. It is also one of the common diseases in my country's citrus producing areas, especially in Guangdong, Guangxi, Hunan and other citrus producing areas. The disease is a bacterial disease. After the citrus is damaged, a crater-shaped lesion with a size of 2-8mm is formed on the leaves, branches, and fruits. In the later stage, it causes leaf and fruit drop, affecting fruit yield and quality. This disease mostly occurs from early April to late November every year, mainly harming spring shoots, summer shoots and autumn shoots, with summer shoots and autumn shoots being the most severely damaged. The germs can infect plants through stomata, lenticels and wounds. Prolifera...
