What Is Probenazole?
Probenazole is a fungicide known for its high effectiveness in inducing disease resistance in plants. It is particularly effective against diseases like rice blast, white leaf blight, bacterial rice blight, and ear blight.
Different application methods are preferred depending on the crop type and growth stage. For rice seedlings, even distribution over the seedling box is necessary, while general spraying is suitable during the field growth stage. For crops like cabbage, full surface soil-mixing is recommended, whereas planting hole soil-mixing suits cucumbers and peppers.
Uses of Probenazole
Probenazole protects crops from pathogen-induced damage, particularly effective against bacterial diseases like black rot and black spot bacterial disease. It’s used on various crops, including broccoli, cucumbers, lettuce, cabbage, and leeks, as well as on rice to prevent rice blast. Conditions such as low temperatures, lack of sunlight, and high humidity can heighten disease risk. However, probenazole is effective against these challenges.
Features of Probenazole
Rice plants absorbing probenazole exhibit resistance to all types of blast diseases, inhibiting infection.
Pros
Initially developed for rice blast, probenazole has also proven effective against bacterial blights in cucumbers, cruciferous vegetables, leeks, etc. Its long-lasting pest control effect reduces labor and enhances early control efficacy.
Disadvantages
The prolonged effect, while beneficial, can also be a drawback. For instance, some vegetable treatments require application 30 to 35 days before harvest, which complicates usage for crops nearing harvest. Misjudging the application timing can also limit its effectiveness, underscoring the importance of careful planning and adherence to recommended usage guidelines.
Types of Probenazole
Probenazole is commonly available in granular form, with packages typically in 3Kg and 10Kg sizes.
How to Select Probenazole
Timing is crucial when using probenazole. In paddy rice, it’s effective for both leaf and ear blast if applied 7 to 10 days before leaf blast symptoms appear. For vegetables, it’s generally used only at planting time, except for leeks, where it can be applied up to 30 days before harvest. Ensure the specific vegetable is registered for probenazole use and note that combinations with other active ingredients may have different registrations.
How to Use Probenazole
As a granular formulation, probenazole is directly sprayed. In rice cultivation, it’s applied in the seedling box, followed by irrigation to remove chemicals from stems and leaves. It’s advised not to use on young or soft, elongated seedlings due to the high risk of chemical damage. Since each crop has specific precautions, it’s recommended to carefully review product instructions before use.
