Abstract
The invention relates to a pesticides fungicide mixture comprising thiophonate-methyl and hexaconazole. The main active components comprise the thiophonate-methyl and the hexaconazole, and the weight ratio of the thiophonate-methyl and the hexaconazole is 10 to 80:1 to 20. The invention has obvious effect for preventing and curing apple leaf spot disease, pear scab, grape powdery mildew and rice sheath blight disease.
Description
Technical field:
The present invention proposes the combination sterilization composition that a kind of active ingredient is thiophanate-methyl and own azoles alcohol, be used to prevent and treat apple, grape, vegetables, wheat, all kinds of diseases of paddy rice.
Background technology:
Because the long-term single spot defoliation that the bactericide that uses certain type is prevented and treated apple tree that depends on of people, be easy to generate pesticide resistance to a great extent, cause the dosage of chemical bactericide sharply to increase, simultaneously environment is caused pollution to a great extent, also increased peasant's drug cost.
The objective of the invention is to by after thiophanate-methyl and own azoles alcohol are carried out being mixed of reasonable science, thereby obtain control apple, grape, vegetables, wheat, all kinds of diseases of paddy rice.Avoided because of with an organic solvent easily producing poisoning, big for environment pollution, difficult transportation and the problem of preserving, and then reduce peasant's use cost greatly, and has obvious role in synergism after thiophanate-methyl and own azoles alcohol are composite, control efficiency obviously is better than the single usefulness of single agent, and does not see the relevant report of thiophanate-methyl and the composite product of own azoles alcohol so far as yet.
Summary of the invention:
The objective of the invention is to propose a kind of thiophanate-methyl and the composite bactericidal composition of own azoles alcohol, it has obvious synergistic effect, has enlarged fungicidal spectrum simultaneously, has reduced use cost, to people and animals, Environmental security, to fruit tree, vegetables and the good bactericidal composition of cereal control efficiency.
The present invention realizes in the following manner:
