Cool temperatures, moist conditions, still air and lack of sunshine favor sporulation spores can occur and advance in any condition of high humidity. kurstaki, Monterey Garden Insect Spray, Entrust.Ĭultural controls: Floating row covers, good weed control.Ĭultural controls: Disinfect greenhouse materials & cages, farming tools & gloves, avoid overhead irrigation, don’t work crop when wet, rotate crops, use compost.ĭry conditions spare us some years, but late blight is here to stay, especially for field-grown crops. Material controls: Bacillus thuringiensis subsp. See if you can get the chickens to eat them. Material controls: MilStop, Copper, Regalia, CeaseĬultural controls: Look for frass (droppings) and handpick. Material controls: Regalia, Copper, MilStop.Ĭultural controls: Rotation, mulching, minimize plant wetness, staking, use compost. Septoria can live over the winter on live tissue, so don't compost affected plants.Ĭultural controls: Space plants for good air circulation. It can be spread by wind or carried on clothing and tools. It can eventually spread to the entire plant in conditions of high humidity and temperatures. It is characterized by yellowing and small circular spots on older leaves. Septoria Leaf Spot can appear almost overnight. Material controls: Regalia, Copper, Cease. Letting plants freeze on soil surface kills LB spores.Ĭultural controls: Destroy cull potatoes & potato volunteers, avoid overhead irrigation. LB on tomatoes is not seed-borne and does not survive on dead tissue. Still later, hard crusty lesions form on fruits. Early in the season, late blight infection shows as roundish lesions on leaves that uniquely will cross the center vein of the leaf. Late Blight usually starts on the foliage of the plant. Do not compost affected plants as EB can overwinter even on dead tissue.Ĭultural controls: Rotation, avoid stressing plants, staking, minimize leaf wetness, mulching, indeterminate varieties are more resistant/tolerant, disinfect stakes & cages. Mulching deters EB by reducing rain splash on foliage.
EB can be managed culturally should not result in significant crop loss. To ensure true-to-type seed, grow open-pollinated varieties and separate by 50 feet.Įarly Blight shows up as drying and dying leaves at the bottom of the plant.
Rinse in a fine strainer and dry seeds on a coffee filter. Ferment uncovered for a few days until the slurry forms a moldy cap. Saving Seed:: Saving tomato seed is easy! Remove stem-end and crush the fully ripe fruit into a container. Organically and sustainably grown seed was rinsed with a sodium hypochlorite solution to reduce risk of seed-borne disease. Good seed retains viability so we often commission two-year productions. Tomato experts Carolyn Male and Kokopelli’s Dominique Guillet both oppose pruning, arguing more abundant foliage provides more photosynthesis. Indeterminate (Ind.) climbing varieties are customarily staked and pruned.Determinate (Det.) bush varieties may be staked, should not be pruned.Instead use generous amounts of well-rotted cow or horse manure or compost to boost plant vigor, and crushed eggshells or gypsum at the bottom of each hole for calcium. Avoid using fresh manure as it causes lush foliage with few ripe fruits. Transplant after frost danger has passed. Minimum germination soil temperature 50°, optimal range 60-85°. 9,000 seeds per oz, 0.1 gram pkt ~30 seeds, 0.2 gram pkt ~60 seeds, 0.5 gram pkt ~150 seeds.Ĭulture: Usually started indoors Feb–April.Days to maturity are from date of transplanting.
