What is the use of the fungicide chlorothalonil?

The method of use is to spray chlorothalonil when there is a related disease, and then spray it every seven days, so that it can have an effect on the crops.

When using it, you must read the instructions, then dilute it according to the proportion, and then put it in a watering can for use.

First of all, it is necessary to choose the right product according to different situations, and then we must pay attention to the appropriate concentration, and at the same time we must absorb it with water, and pay attention to the safety distance when spraying, and do not spray too much at one time.

Chlorothalonil is a pesticide that targets fungal diseases to which fruit trees and vegetables are susceptible. Highly effective, broad-spectrum fungicide with protective effect. It is stable to weak acid, weak alkali and light and heat, and has no corrosive effect.

It is easy to adhere to the surface of the plant, resistant to rain washing, and the residual effect period is generally 7-10 days. It is mainly used for the prevention and control of rust, anthracnose, powdery mildew and downy mildew on fruit trees and vegetables.

When should chlorothalonil not be used

The young fruits of the apple flowers within 20 days are not suitable for medicine, and it is easy to cause drug damage, and some yellow varieties of apples, especially the golden handsome species, will form rust after medication. Pear trees should not be used, otherwise it will cause pesticide damage. It can be applied at the bud stage and after flowering, and should be used with caution at the young fruit stage, as it will cause rust when the concentration value is high.

Grape and red grapes, green grapes are pesticide damage in the young fruit stage, and some yellow species are pesticide damage, which will cause rusty fruits, and the use of fruits after bagging is not a big problem.

Flowers are easy to cause pesticide damage to plum blossoms and roses. Mixed with pine borer, it is easy to produce pesticide damage on fruit trees; Mixed with Gram mite, tricyclic tin is more likely to cause pesticide damage on Camellia oleifera trees. Persimmon is sensitive to chlorothalonil and cannot be used.

Chlorothalonil is also highly toxic to fish and bees, so chlorothalonil should be used with caution in rice fields and is not suitable for use before and after the flowering period of crops. Oil substances may aggravate the pesticide damage, in the case of mixing potions, it is not suitable to add raw oil modifiers, and it should be noted at the same time when mixing with emulsifiable concentrate traditional Chinese medicine preparations.

Many studies have found that macroscots and mice with chlorothalonil will produce renal function epithelial cell tumors after long-term ingestion of large amounts of chlorothalonil, indicating that chlorothalonil still has a certain risk of toxicity to humans. Therefore, chlorothalonil is not suitable for large applications on the eve of crop picking (within 7 days). Although chlorothalonil has many benefits, the above situation is not to use chlorothalonil, and everyone must memorize it.

Regarding the conditions under which chlorothalonil cannot be used, I will explain it to you, I hope it will be of some help to you.

Chlorothalonil is a broad-spectrum, protective agent, widely used in fruit trees, vegetables and cash crops to prevent and control downy mildew, anthracnose, leaf mildew and other diseases.

After spraying on the plant body, it can have good adhesion on the body surface and is not easy to be washed away by rain, so the effect period is longer.

So, what diseases does chlorothalonil fungicide treat? What are the functions and uses of chlorothalonil? Let's find out together.

What diseases are treated with chlorothalonil fungicide, chlorothalonil mainly treats fungal viruses such as blast, leaf rust, leaf spot, peanut rust, brown spot, black spot, downy mildew, etc.

Applicable crops are grapevines, pear trees, apple trees, jujube trees, persimmon trees, tomatoes, cucumbers, wheat, rice, cabbage, etc.

When using this agent, the effect of the initial application is best.

The effect of chlorothalonil 1, the pure product of chlorothalonil is white crystal, is a high-efficiency, low-toxicity broad-spectrum fungicide, the efficacy is relatively stable, the effective period is long, the toxicity to humans and animals is low, and the toxicity to fish is greater.

2. The agent can prevent and control a variety of fungal diseases, and the use of chlorothalonil has a significant effect on the prevention and control of carbendazim, but it has no effect on the prevention and control of diseases caused by soil-borne Pythium.

The use of chlorothalonil 1, chlorothalonil is a protective fungicide, can prevent and control rice, fruit trees, wheat, vegetables, tea and peanuts and other diseases, such as wheat gibberell hail shoot disease, 100 square meters can use 75% wettable powder about 135-150 grams, mixed with 6 kg of water for spraying.

2. Vegetable diseases, such as late blight, leaf mold, spot blight, etc., can use about 135-150 grams of 75% wettable powder, sprayed with 60-80 kg of water, and fruit tree powdery mildew, downy mildew, can use about 75-100 grams of 75% wettable powder, sprayed with 30-40 kg of water.

3. In addition, it can also prevent and control potato late blight, eggplant gray mold, blue downy mildew, black spot, mesh cake source repentance, peanut leaf spot, rubber canker, peach rot, scab, tea anthracnose and so on.

Summary. No. Chlorothalonil is acidic, but it can be killed by copper hydroxide, which is alkaline, and acidic pesticides and alkaline pesticides cannot be mixed.

This question is up to me, it takes a little time to type, and please be patient No. Chlorothalonil is acidic, but it can be killed by copper hydroxide, which is alkaline, and acidic pesticides and alkaline pesticides cannot be mixed.

Specifically, what varieties can be mixed with which varieties must first identify the acidity and alkalinity of the pesticide and its use for crops.

If these two are used together, the performance of pesticides will be greatly reduced, and the crops will be damaged.

I hope mine is helpful to you and I wish you all the best and all your wishes come true! I wish you a happy life, hope
