Detailed interpretation of fungal fungicide enoylmorpholine

<

Main dosage form

50% dimethomorph wettable powder, 69% dimethomorph-manganese zinc wettable powder, 55% dimethomorph-fucoble powder, 50% water dispersible granule

Function characteristics

It is a special fungi fungus fungicide . Its function is to destroy the formation of cell wall membrane. It has a role in all stages of life history of oocysts, especially in the formation stage of sporangia and oospores, at very low concentration. Lower (<0.25 μg/ml) is inhibited. No cross-resistance with phenylamide agents.

Features

Dimethomorph is a new type of systemic therapeutic low-toxic fungicide. Its mechanism of action is to destroy the formation of the cell wall membrane of the pathogen, causing the decomposition of the sporangia wall and causing the bacteria to die. In addition to zoospores formation and spore swimming period, it has effects on all stages of life history of oocysts, especially for the formation stage of sporangia and oospores. If the drug is used before the formation of sporangia and oospores, Spore production can be completely inhibited. The drug has strong systemic attraction, and the root can be applied to all parts of the plant through the root; the leaves can be sprayed into the interior of the blade. It has no cross-resistance with benzamide fungicides such as metalaxyl.

Action object

The enoylmorpholine is a special agent for controlling fungal diseases of the oomycetes, and has low fungal diseases such as downy mildew, Phytophthora capsici, late blight, blight, rot, rot, and black shank. Very good control effect. Can be applied to grapes, lychee, cucumber, melon, bitter gourd, tomato, pepper, potato, cruciferous vegetables.

Way of use

The enoylmorpholine is mainly used to control the disease by spraying, and the root and neck damage can also spray on the root neck and its surrounding soil. When controlling grape, litchi or root-neck disease, generally use 5% to 2,000 times of 50% water-dispersible granules, or 20,000 to 3,000 times of 80% water-dispersible granules, or 1000% of water-dispersible granules. 1500 times liquid, or 25% wettable powder 800~1 000 times liquid, or 10% water emulsion 300~400 times liquid, spray or spray; prevent diseases of melons, solanaceous fruits, leafy vegetables and tobacco crops At the time, generally 35 to 50 grams of active ingredient per 667 square meters of spray, 30 to 60 liters of water spray. It is effective when the disease occurs before or at the beginning of the disease.

Agricultural application

It is widely used for disease control of vegetable downy mildew, epidemic disease, seedling stage disease, tobacco black shank, etc. caused by the fungus of the genus Escherichia, with systemic activity. Under the premise of not considering the resistance of pathogenic fungi, the efficacy is higher than that of currently used metalaxyl, cymoxanil, ethylphosphorus, and vesyl cream.

It has a relatively high risk of resistance when used alone, so it is often used in combination with protective fungicides such as mancozeb to delay the development of resistance.

Precautions

1. When the cucumber, pepper, cruciferous vegetables, etc. are young, the amount of liquid spray and the amount of the drug are low. Spray the drug to evenly cover the blade.

2. Wear protective clothing when applying the medicine to avoid direct contact with the body parts.

3. If the drug is stained with the agricultural paper, wash it with soap and water. If splashed into your eyes, rinse quickly with water. If you are mistaken, don't induce vomiting and send it to hospital for treatment as soon as possible. This medicine has no symptomatic treatment of antidote.

4, the drug should be stored in a cool, dry and away from feed, children.

5, each season of crop Anke-manganese zinc should not be used more than 4 times, pay attention to the use of other fungicides with different mechanisms of action and their rotation applications.
