What to Do When Grapes Suffer Pesticide Damage
During the cultivation of grapes, improper use of pesticides often leads to pesticide damage, causing significant losses in yield and quality. So, what should be done when grapes suffer pesticide damage? How to prevent (D-P) harm? Let's find out together.
Reducing Drug Damage
The main damage to grapes occurs on the leaves, sometimes on the fruits and young branches. The specific symptoms of damage vary significantly among different varieties. As soon as pesticide damage occurs, quickly water the plants to reduce the concentration of the pesticide and minimize the damage. If pesticides and herbicides are sprayed on the ground, they should be watered and rinsed promptly to remove any remaining pesticides in the soil. This can greatly reduce the harm to grapes. Spraying acetamide or Neptune can also mitigate the damage.
Proper Use of Pesticides
When using pesticides, it is important to choose safe ones and strictly follow the concentration instructions provided. Do not arbitrarily increase the concentration and avoid using them when the temperature is too high or when the plants are wet with dew or rain. If using a wettable powder, the pesticide must be diluted evenly. When combined with foliar fertilizers, the fertilizer should be fully dissolved before adding it to the pesticide solution, then stir thoroughly before spraying.
Strengthening Management
To improve the resistance of grapes to pesticides, it is necessary to strengthen management and cultivate strong seedlings. After the pesticide damage is resolved, it is essential to increase fertilization and watering to help the plants recover quickly. For minor damage, remove the affected leaves or fruits to prevent opportunities for pathogens. For extensive damage, measures to control pests and diseases should be taken while mitigating the pesticide damage. At this time, due to chemical damage to the grapes, the plants are weakened and have low resistance to diseases. The occurrence of pests and diseases can easily lead to plant death.
