After the frost had fallen, it was time to enter the season of harvesting and harvesting. In the past few days, there were farmers talking on the phone. The radish that they planted each year was found to be serious late in the growing season. Is there a way to prevent this disease?

The dry shoot is a perennial herb and is a heat-clearing and detoxifying Chinese medicine. In the Chinese herbal medicine market, it is relatively popular and the planting efficiency is high. Rust is most likely to occur when planting shoots. After infection with rust, the leaves begin to age and dry ahead of time, seriously affecting the photosynthesis of the plants, affecting the underground rhizomes and causing a direct loss of production.

Prevention and cure of dry rust can adopt physical prevention and chemical prevention methods. At present, we should seize the opportunity of harvesting and dry shoots. We should collect the diseased leaves and wilted petioles to burn and bury them deeply. Rhizome propagation was harvested one year after planting, and nursery colonization was harvested in the third year. Most of the shoots were harvested in the late October or early November when the upper plants all died. The growers can first collect the dead leaves from the upper part and collect it in a place where they are burned. This has a good preventive effect on the reduction of rust in the coming year.

In addition, it should be understood that the incidence of dry rust, to understand the characteristics of the incidence of rust. In fact, the dry rust disease is mostly affected by the climate from the seedling and adult stage, but it is only light in the early stage of disease, and it is more obvious to damage the leaves in the autumn. At the beginning of the disease, 95% of the enemy's rust sodium can be sprayed 400 times, spraying once every 7-10 days, spraying 1-2 times in succession; spraying 15% Triadimefon 1000 times, or 50% rustin EC 800 times , Or 70% of new Wansheng WP 600 times, or 25% of the enemy demulsification oil 3000 times, spraying every 5-7 days, and even spray 2-3 times.
