Abstract
The invention relates to a fungicide containing copper gluconate, which is characterized in that, based on the total mass fraction of 100%, it consists of 0.01-0.07% of copper gluconate, 0-0.015% of fungicide, 0-0.057% of auxiliary agent, and the balance water composition. The fungicide of the present invention can be well dispersed in the water medium, and can effectively prevent and treat plant diseases, especially bacterial diseases, such as citrus canker, litchi downy mildew, anthracnose, cabbage black rot, cucumber horn spot etc., and it has a promoting effect on crop organisms and has no stimulating effect on pests. The medicinal liquid is mixed with water and sprayed to the crown of the tree. It has good diffusion on the leaf surface and low toxicity, so it has great promotion value.
Description
technical field [0001] The invention relates to a bactericide, in particular to a bactericide containing copper gluconate. Background technique [0002] Copper fungicides have a unique control effect on crop bacterial diseases. At present, there are two main types, one is inorganic copper preparations, such as copper sulfate, Bordeaux mixture, copper hydroxide, copper oxychloride, etc., and the other is organic Copper preparations, such as copper succinate, copper rosinate, copper chlorobacteria, copper thiabium, copper acetate, copper amino acid, copper citrate, copper humic acid, copper naphthenate, copper benzoate, copper quinolate, imine Copper salt of fresh amine, copper terephthalate, copper butenedioate, etc. Studies have shown that inorganic copper preparations are easy to stimulate the occurrence of pests, such as citrus panonychia. Although organic copper fungicides will not or less induce pest outbreaks, most of them are insoluble in water, so they can usually on...
