Embodiment 1

[0019] Prepare 30% propineb and hexaconazole wettable powder, the process is:

[0020] Propineb 29g

[0021] Hexaconazole 1g

[0022] Sodium dodecylbenzenesulfonate 10g

[0023] Calcium Lignosulfonate 8g

[0024] Sodium Benzoate 1g

[0025] Organic silicone 0.5g

[0026] Silica 50.5g

[0027] Thoroughly stir, mix and grind to make 30% propineb and hexaconazole wettable powder, prevent and treat the spotted leaf disease of apple trees, dilute and spray by 1000 times, and compare after 3 to 7 days.

Embodiment 2

[0029] Prepare 50% propineb and hexaconazole water dispersible granules, the process is:

[0030] Propineb 48g,

[0031] Hexaconazole 2g

[0032] Sodium Lauryl Sulfate 10g

[0033] Sodium Lignosulfonate 8g

[0034] Calcium chloride 0.5g

[0035] Kaolin 31.5g

[0036] Thoroughly stir, mix, dry, and granulate to make 50% finished products of propineb and hexaconazole water-dispersible granules, to prevent and treat the spotted leaf disease of apple trees, dilute and spray by 1500 times, and carry out after 3 to 7 days control.

Embodiment 3

[0038] Prepare 70% propineb and hexaconazole suspension concentrate, the process is:

[0039] Propineb 65g

Abstract

The invention discloses a composition having tericidal action which has the active ingredients of propineb and Hexaconazole which have the weight proportion of 10-80:1-30; according to a plurality times of formulation screening test, the optimal mixture ratio is 50-70:3-5; the composition has remarkable control effect on alternaria leaf spot, phoma citricarpa and anthracnose of apple trees.

Description

Technical field: [0001] The invention relates to a fungicide composition and its application, which is a fungicide composition with propineb and hexaconazole as main active ingredients, and belongs to the technical field of pesticides. Background technique: [0002] Propineb is a broad-spectrum protective organosulfur fungicide. Its bactericidal principle is the same as that of mancozeb, mainly inhibiting the oxidation of pyruvate in pathogenic bacteria. The main dosage form of the product is wettable powder. The trade name of the foreign product is Antaisheng. This crop is mainly used to control apple tree leaf spot, scab, anthracnose and vegetable downy mildew. [0003] Hexaconazole is a high-efficiency fungicide among triazoles. Its biological activity and bactericidal mechanism are basically the same as those of triadimefon and triadimenol. It has strong inhibitory effect, strong permeability and systemic transport ability, and can quickly penetrate into various parts a...
