Symptoms of herbicide damage in watermelon: the seedling leaves turn dull gray, the leaf surface is uneven with bumps and wrinkles and feels stiff, the vines are thin and the leaves become smaller, and plant growth is inhibited. The cause of the damage is that a "broadleaf-killing herbicide" sprayed on neighboring plots spreads through the wind. Even if there is no wind drift of the chemical when the neighboring plot is sprayed, after a soaking rain, fog can also carry the chemical odor and cause the damage to occur.
Control method: herbicide damage control should focus on prevention. During the period of heavy herbicide spraying, use Jinyuanbao liquid fertilizer (or other foliar fertilizer) as a foliar spray once every 5-7 days to prevent the damage. For "watermelon and melon" seedlings that have already suffered damage, take measures of spraying to relieve the damage; choose Jinyuanbao liquid fertilizer mixed with "Virus Source U" or "Virus Source Powder" and spray it on the leaves to treat it. It takes effect noticeably in two days, gradually returning watermelon and muskmelon seedlings to normal, with sturdy seedlings and well-proportioned fruit shapes.
