What to Do If a Peach Tree Gets Peach Leaf Curl? A Detailed Guide to Prevention and Control Methods

Agricultural Prevention and Control of Peach Leaf Curl

When establishing a new peach orchard, choose varieties that are both high-yielding and high-quality as well as disease-resistant. For peach orchards that have entered the fruiting stage, manage soil, fertilizer and water well, prune and shape carefully, and improve ventilation and light conditions. Orchards with severe outbreaks should be top-dressed and irrigated in a timely manner, and sprayed with Guaguo Zhuangdiling to thicken the nutrient transport vessels, strengthen tree vigor and improve disease resistance. In April and May, in conjunction with growth-period pruning and control of peach red-necked longhorn beetle larvae, remove any leaves showing leaf curl immediately and burn them in a centralized manner. Spray a 1000-fold dilution of Hushu Jiangjun for sterilization and disinfection, inhibiting the spread and replication of the pathogen.

The Best Pesticides for Controlling Peach Leaf Curl

During the dormant season, spray a 1000-fold dilution of Hushu Jiangjun to eliminate overwintering pathogens. When peach buds begin to swell in spring, this is the key period for controlling peach leaf curl; spray a 1000-fold dilution of Hushu Jiangjun, or a 1000-fold dilution of 70% thiophanate-methyl wettable powder, or a 1000-fold dilution of 50% carbendazim suspension concentrate. During the peach tree growing season from March to June, that is, after leaf expansion and before the arrival of hot, dry weather, you can use thiophanate-methyl or carbendazim with added Xin Gao Zhi Mo, which helps retain heat and moisture and enhances pesticide efficacy. In the early stage of leaf curl, lesions are about 0.2 cm in diameter; spraying fungicide noticeably suppresses the lesions.
