What to Do When Grapes Suffer Herbicide Damage? The Latest Remedial Methods
During the cultivation of grapes, herbicide damage often occurs due to improper use of chemicals, causing considerable losses to grape yield and quality. So what should be done when grapes suffer herbicide damage? How can herbicide damage be prevented? Let's take a look together.
1. Alleviating herbicide damage
Herbicide damage in grapes mainly shows on the leaves, and sometimes also occurs on the fruit and young shoots. The specific symptoms of herbicide damage vary noticeably depending on the variety. After herbicide damage occurs, the affected plants should be sprayed with clean water as soon as possible, reducing the occurrence of herbicide damage by lowering the chemical concentration. If it is a pesticide, herbicide, etc. sprayed on the ground, irrigation should be carried out promptly to wash the soil, rinsing away the residual pesticide in the soil. In this way, grape herbicide damage can be greatly alleviated. Alternatively, spraying propionyl brassinolide aqueous solution or Sea Elf can also alleviate herbicide damage.
2. Rational use of chemicals
When using pesticides, choose safe pesticides as much as possible, and be sure to prepare the spraying concentration according to the instructions. Do not arbitrarily increase the concentration, avoid using chemicals when the temperature is too high, and do not use chemicals immediately when there is dew or after rain. If it is a wettable powder pesticide, it must be diluted evenly. When using it together with foliar fertilizer, first fully dissolve the foliar fertilizer before adding it to the liquid chemical, and stir it thoroughly before spraying.
3. Strengthening management
During grape cultivation, management should be strengthened and strong vines should be cultivated to improve the grape's tolerance to chemicals. After herbicide damage is alleviated, fertilizer and water should be increased to promote the plant's recovery as quickly as possible. For small-area herbicide damage that has already occurred, the affected leaves or fruit can be removed to avoid giving pathogens an opportunity. If it is large-area herbicide damage, while alleviating the herbicide damage, pest and disease control measures should also be taken. This is because after grapes suffer herbicide damage, the plant's vigor weakens and its resistance to diseases is relatively weak. If pests and diseases occur at this time, it can very easily lead to plant death.
