Problems solved by technology

At present, copper preparations are mostly used to prevent mango bacterial diseases by spraying. Generally, spraying protection is carried out after fruit trees are pruned or before the arrival of typhoons and rainy seasons. Continuous spraying is required for multiple times to prevent and control, but most of the control effects are not ideal. , and often due to improper use, it is easy to cause local copper ion concentration to be too high, resulting in phytotoxicity, light leaves fall, severe ones die; if it rains after spraying, the medicament is washed away and needs to be re-sprayed

Embodiment 1

[0029] A granule for preventing and treating bacterial diseases of mangoes. The weight percent of components is: 5% copper rosinate, 30% starch-based water-retaining agent, 40% bentonite, 5% talcum powder, and 20% humic acid. The ingredients are pulverized, the binder is firstly mixed with the water retaining agent, and then other components are added and mixed evenly; the mixed powder is pressed into tablets or granules, sieved, and the unformed powder is mixed evenly and pressed.

Embodiment 2

[0031] A granule for preventing and treating bacterial diseases of mangoes, the composition weight percentage is: copper acetate 15%, starch-based water-retaining agent 42%, glucose 10%, bentonite 10%, alginate 5%, calcium stearate 0.5%, borax 2%, potassium sulfate 15.5%. The ingredients are pulverized, the binder is firstly mixed with the water retaining agent, and then other components are added and mixed evenly; the mixed powder is pressed into tablets or granules, sieved, and the unformed powder is mixed evenly and pressed.

Abstract

The invention discloses a granule for preventing and treating mango bacterial disease and a preparation method thereof, and belongs to the field of pesticide preparations. The granule comprises a particle or tablet formed by performing mixing and pelleting on the following components in percent by weight: 5 to 30 percent of a copper preparation, 30 to 70 percent of a water-retaining agent, 20 to 50 percent of an adhesive, 0.1 to 5 percent of a lubricant, and 0.5 to 20 percent of nutritional ingredient. The preparation method comprises the following steps: crushing all the components, firstly uniformly mixing the adhesive and the water-retaining agent, then adding other components, and uniformly mixing; pressing uniformly mixed powder into tablets or particles, sieving, uniformly mixing uniformed powder, and pelleting. The granule is good in bactericidal effect, long in the effective duration of fungicides and good in control effect; pesticide hazard cannot be produced, and leaves and fruit surfaces cannot be damaged; and the granule is simple and convenient to apply, and high in working efficiency.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to a pesticide preparation for preventing and treating mango bacterial diseases. Background technique [0002] Bacterial angular leaf spot, also known as bacterial black spot or canker, is the main bacterial disease on mangoes, and it commonly occurs in major mango producing areas such as Sichuan, Guangdong, Guangxi, Yunnan, Hainan and Fujian. Mainly damage leaves, branches, flower buds, flower spikes and fruits. Small black spots the size of needleheads appear on the infected leaves of unturned green shoots, and then expand into small raised black spots with yellow halos around them. The spots are polygonal, and later the spots merge into irregular large black spots. Longitudinal streaks. There are needle-like black dots on the fruit skin at the beginning of the fruit infection, and then expand into crater-shaped dark brown ulcers, which are easy to induce the invasion of an...
