Benzopyrazole, also known as benzene ether methoxazole-pyrimethanil, is a composite broad-spectrum fungicide composed of benzene ether methoxazole and pyrimethanil. It is commonly used by farmers as a pesticide. Below, we'll introduce the correct use of benzopyrazole. Let's take a look.
Correct Use of Benzopyrazole
1. Application Method
The most common method of using benzopyrazole is through spraying on crops. For the best effectiveness and safety, it is generally recommended to start applying the pesticide at the early stage of crop disease. Depending on the actual effectiveness in disease prevention, it can be applied continuously for about 2-3 times. There should be a safety interval of 7-10 days between each application, and the maximum number of applications throughout the crop's growth season should not exceed 3 times.
2. Dosage and Concentration
Using 30% benzopyrazole suspension concentrate as an example, the general dosage per acre can be diluted with 30 kilograms of water per 10-25 milliliters for spraying. The specific dosage depends on the severity of the disease and the type of crop.
-
For melons, vegetables, and economic crops, the dosage is recommended to be slightly less, while for field crops and fruit trees, it is recommended to be slightly more. If unsure, a dosage of 15 milliliters per acre can be used.
-
When treating fungal diseases in fruit trees, the concentrate should be diluted 1500-2500 times before use.
-
When treating fungal diseases in field crops, the concentrate should be diluted 1500-2000 times before use.
-
When treating fungal diseases in melons, vegetables, and fruits, the concentrate should be diluted 2000-3000 times before use.
3. Precautions
-
When using benzopyrazole fungicides, always check the formulation and effective ingredient content, and strictly follow the recommended dosage and concentration range.
-
Avoid mixing benzopyrazole with alkaline drugs or copper formulations. Especially, when preventing tree diseases, avoid using it with lime sulfur or Bordeaux mixture, as these are both alkaline drugs.
-
Avoid long-term continuous use of benzopyrazole alone. Rotate its use with 2-3 other drugs. Even the best drug, if used continuously for a long time, can lead to drug resistance in pathogens, reducing its effectiveness over time.
-
Avoid using benzopyrazole during bee pollination periods or on silkworm mulberry crops. Also, avoid using it near water sources or aquaculture areas, as benzopyrazole has certain toxicity to bees, silkworms, fish, etc.
Above are the correct methods of using benzopyrazole. Farmers should take personal protective measures when using benzopyrazole and adhere to the recommended methods and precautions.
