How to prevent peony pests and diseases?
The common diseases of peony include erythema, gray mold, brown spot, rust, anthrax, and white tinea. During the entire cultivation process of peony, pests and diseases are often caused by various factors such as climate, soil re-entry and poor management, which may damage the normal growth and development of peony, weaken its growing condition, decline its color, produce low yield, and have poor quality. Therefore, strengthening the prevention and control of peony pests and diseases is an important measure to ensure its robust growth.
The prevention and control method of the above-mentioned diseases is: dipping the roots with 500 times 70% thiophanate-methyl 800-fold solution of new high fat film for 10 minutes before planting. After the onset of the disease, use 50% carbendazim 800 times and 800 times the new high-fat membrane spray. Rust disease must be sprayed with 300 times the enemy rust sodium. The pests of peony are not much, mainly scale insects, cockroaches, leaf roller moths and so on. The bite of peony roots and necks is more common and serious. When larvae and other underground pests are harmed, 5% phoxim granules (2 kg per acre) can be uniformly applied to the soil surface, and then turned into the soil (about 20 cm), and the control effect is good.
In the entire prevention and control process, prevention and prevention are the main methods to be adopted. Attention should be paid to the application of traditional bactericides such as lime sulfur and Bordeaux mixture. The addition of new high-fat membranes to these bactericides will result in low cost and good results. It has also been observed that some arbors, apricots, and other arbor species within the peony plots can effectively reduce the occurrence of leaf diseases and promote the growth potential, which may be the result of long-term adaptation of the peony to its natural environment in its place of origin.
