Precautions on vegetable medication

First, focus on the rational use of pesticides to delay the development of resistance.

　　 1. Avoid using a single pesticide for an extended period. Continuous use of the same type of pesticide can lead to pests developing resistance, reducing its effectiveness over time. Alternating between different types of pesticides helps prevent resistance and improves overall control.

　　 2. Ensure the correct dosage and concentration are used when preparing the pesticide solution. Using too high a concentration can result in excessive residue, which may harm plants or even cause phytotoxicity. Always follow the manufacturer's instructions precisely to avoid these issues.

　　 3. Control the number of applications and maintain a proper interval between them. Applying pesticides too frequently or with short intervals can lead to plant stress, reduced effectiveness, and increased resistance development. It is important to follow a planned schedule for optimal results.

Second, pay attention to disease prevention during critical periods and implement early measures.

　　 1. During the seedling stage, young plants have weak immunity and are highly susceptible to diseases. Applying a protective fungicide at this stage helps prevent infections and ensures healthy growth.

　　 2. After transplanting, plants grow rapidly, making them more vulnerable to diseases. A preventive spray should be applied to create a protective barrier around the plant, helping to block pathogen entry.

　　 3. During the fruiting stage, when the plant transitions from vegetative to reproductive growth, leaves may become nutrient-deficient and more prone to disease. Timely application of pesticides is essential to protect the crop.

Third, improve spraying techniques to ensure effective treatment.

　　 1. Ensure thorough and even coverage during spraying. Avoid over-spraying or missing areas. Begin from the bottom of the plant and move upward, ensuring that both sides of the leaves are fully covered.

　　 2. Focus on spraying the most vulnerable areas. Target the central parts of infected plants and the upper and middle leaves, as these are more likely to be affected by disease.

　　 3. Choose the right time for spraying. Spraying during periods of strong light, high temperature, and high humidity is ideal because it allows the pesticide to be absorbed more effectively. However, avoid spraying during midday when the sun is strongest, as this may cause damage or reduce the effectiveness of the product.
