Kind of watermelon pay attention to prevent phytotoxicity
Watermelon plants grow vigorously and have a high water content, making them sensitive to various chemical agents. If the concentration of applied chemicals is too high or if the wrong product is used, it can easily lead to phytotoxicity. Here are some effective remedies to address such issues:
First, flushing with water is one of the most immediate and effective methods. As soon as symptoms appear, use a sprayer to thoroughly rinse the stems and leaves with water. This helps remove any chemical residue that may still be on the plant surface, reducing the risk of further damage. Ensure that the pressure from the sprayer is strong enough and that a large volume of water is used for optimal results.
Another method involves using potassium permanganate. If the injury occurs due to chemical exposure, apply a diluted solution of potassium permanganate at a ratio of 5000:1 to 7000:1. This can help neutralize the harmful effects and reduce the severity of the damage.
To prevent further harm, it's important to minimize the use of chemical pesticides, especially those with similar properties, until the phytotoxicity has fully subsided. Avoid applying additional chemicals during this time, as they could worsen the condition of the plant.
In addition, proper management after phytotoxicity is crucial. Apply quick-acting fertilizers along with regular watering to promote recovery. Loosen the soil around the plants to improve root aeration and encourage healthy growth. You can also combine root feeding with foliar applications of phosphorus and potassium-based fertilizers to enhance the plant’s overall health and improve its ability to absorb nutrients.
For example, you can prepare a solution by mixing 1 kg of superphosphate with 40 to 50 kg of water. Let the mixture soak overnight, then use the clear liquid to spray the leaves of the watermelon plants. This will support their normal development and help restore their vitality.
By following these steps, watermelon plants can recover more quickly from phytotoxic damage and resume healthy growth. Always monitor the plants closely and adjust your care routine as needed.
