Problems solved by technology

[0002] Since people rely solely on the use of certain types of fungicides for the prevention and treatment of leaf spot of apple trees for a long time, it is easy to produce drug resistance to a large extent, resulting in a sharp increase in the amount of chemical fungicides, and at the same time causing a great degree of environmental damage. The pollution on the ground also increases the cost of medicines for farmers

example 1

[0013] Example 1: the preparation of 20% difenoconazole and zinc zinc wettable powder, the distribution ratio of each component is by weight:

[0014] Difenoconazole 10g

[0015] Zinc 10g

[0016] Sodium Lauryl Sulfate 2g

[0017] Alkane Sulfonate 8g

[0018] Silica 8g

[0019] Kaolin balance

[0020] Mix and grind each component to obtain the product, dilute 1000 times and spray to prevent and control apple leaf spot disease. After 5 days and 10 days, the control rate reaches 75.2%-78.6% and 80.2%-83.2% respectively.

example 2

[0021] Example 2: the preparation of 45% difenoconazole and zinc zinc wettable powder, the distribution ratio of each component is by weight:

[0022] Difenoconazole 10g

[0023] Zinc 35g

[0024] Sodium Lauryl Sulfate 3g

[0025] Alkane Sulfonate 7g

[0026] Silica 8g

[0027] Kaolin balance

[0028] The components are mixed and finely ground to obtain the product, which is diluted 1000 times and sprayed to prevent and control apple tree spot defoliation. After 5 days and 10 days of observation, the control rates reach 80.9%-84.3% and 86.2%-90.1% respectively.

example 3

[0029] Example 3: the preparation of 75% difenoconazole and zinc zinc wettable powder, the distribution ratio of each component is by weight:

[0030] Difenoconazole 30g

[0031] Zinc 45g

[0032] Sodium Lauryl Sulfate 3g

[0033] Alkane Sulfonate 7g

[0034] Silica 8g

[0035] Kaolin balance

[0036] Mix and grind each component to obtain the product, dilute 1500 times and spray to control apple leaf spot disease. After 5 days and 10 days, the control rate reaches 83.5%-85.8% and 88.5%-91.6% respectively.

Abstract

The present invention relates to a pesticide bactericide mixture composed of difenoconazole and dithane, wherein the main active components are difenoconazole and dithane of which the weight ratio is 1-60:1-80. The mixture of the invention has the great effect on controlling alternaria leaf spot, scab and anthracnose of apple tree.

Description

Technical field: [0001] The invention proposes a compound bactericidal composition whose active ingredients are difenoconazole and zinc zinc, which has a good control effect on apple tree spot defoliation. Background technique: [0002] Since people rely solely on the use of certain types of fungicides for the prevention and treatment of leaf spot of apple trees for a long time, it is easy to produce drug resistance to a large extent, resulting in a sharp increase in the amount of chemical fungicides, and at the same time causing a great degree of environmental damage. The pollution on the ground has also increased the cost of farmers' medicines. [0003] The purpose of the present invention is to obtain the best medicine for treating apple tree leaf spot by rationally and scientifically mixing difenoconazole and zinc zinc, thereby greatly reducing the dosage and cost of medicine used by farmers, and reducing the cost of medicine. Environmental pollution problems caused by ...
