Many of these will do better if sprayed with fungicide the first year or two after planting.

Cultivars available today are selections from formal and informal breeding programs, chance discoveries by various growers, or propagated from trees planted by pioneers which have survived for decades. Trees die in 2 to 3 years from repeated defoliation.Ĭultural control Resistant cultivars offer the best option for home gardeners and can be useful for commercial growers. Ultimately, many infected leaves are shed. Some infected leaves drop others remain throughout the growing season, gradually becoming dark brown and heavily coated with spores. Infected twigs occasionally are distorted, and a few fruit may show a reddish growth on the surface. The puckered areas are brightly colored with reds and/or purples and may continue to develop a dusty white coating of spores. As leaves expand they become deformed, puckered, and thicker than normal. Symptoms The first visibly infected leaves are yellow to reddish and somewhat thickened and crisp in texture. Rainfall of 0.5 inch and wetness of 24 hours is needed for fruit infection. Fruit are susceptible after petal fall until air temperature remains above 61☏. Although infected, symptoms may not appear if temperatures rise and remain above 69☏. Maximum infection occurs when trees are wet for 2 days or more, a frequent occurrence west of the Cascade Range. Wetness from rain (or other factors) for over 12.5 hours is needed for leaf infection but only when the temperature is below 61☏ during the wet period. Defoliation from severe infections weakens trees to the point that, if not controlled, they may die in 2 to 3 years. Photosynthetic function of infected leaves is reduced, the leaf imports sugars, and the contents of non-structural carbohydrates and enzymes involved in their metabolism are similar to sink leaves. East of the Cascade Range, after the initial spring infection and the shedding of diseased leaves, no further evidence of the disease is visible. In wet seasons, the fungus continues to cause slight summer infection, particularly west of the Cascade Range. Maximum susceptibility is between bud break and petal fall. Slow growing shoots and leaves can be infected during cool and wet growing seasons. Infection occurs through bud scales in mid- to late winter just as buds begin to swell.

Spores of this fungus overwinter on bark, twigs, and old infected leaves. *Westwood Village, Brentwood Village, Bel Air, Beverly Hills, Culver City, Century City, Hollywood, North Hollywood, Inglewood, Manchester, Marina Del Rey, Playa Del Rey, Playa Vista, Rancho Park, Santa Monica, San Fernando Valley, Venice, Westchester, Westside Village and Malibu.Cause Taphrina deformans, a fungus.
