Fluopyram 17.7% + Tebuconazole 17.7% SC is a mixture of two fungicides that have been widely used to control tip burn in onions. Tip burn is a common fungal disease that affects the leaves of onion plants, causing them to turn yellow and wither. This disease is caused by a fungus called Botrytis squamosa, which thrives in warm and humid conditions.
To effectively control tip burn, it is recommended to use a combination of two fungicides, namely Fluopyram and Tebuconazole. Fluopyram is a systemic fungicide that works by inhibiting the growth of fungi, while Tebuconazole is a contact fungicide that penetrates the plant tissue and kills the fungus. The combination of these two fungicides provides excellent protection against Botrytis squamosa and other fungal diseases.
The recommended dose of Fluopyram 17.7% + Tebuconazole 17.7% SC for controlling tip burn in onions is 400-500 mL per hectare. This dose should be applied as a foliar spray at the onset of the disease or when the environmental conditions are favorable for the development of the disease. The spray should be applied uniformly on the onion leaves, and care should be taken to avoid spraying on the flowers or developing fruits.
It is also important to note that Fluopyram 17.7% + Tebuconazole 17.7% SC should be used in accordance with the label instructions, and personnel applying the fungicide should wear protective clothing, goggles, and gloves. Additionally, if the product comes into contact with the skin, it should be washed off immediately with soap and water, and if it gets into the eyes, it should be rinsed with water for at least 15 minutes.
In conclusion, Fluopyram 17.7% + Tebuconazole 17.7% SC is an effective fungicide mixture for controlling tip burn in onions. However, it should be used in accordance with the recommended dose and label instructions to ensure maximum effectiveness and safety. If you are unsure about the use of this product, it is recommended to seek advice from a licensed agronomist.
