Virtually all soil borne pathogens and nematodes overwinter and will build up from year to year if a suitable host is present. Nematode-induced production problems generally arise from a reduction in root mass and the related decreased efficiency of water and nutrient uptake. Description: Brown to black spots first appear on lower leaves, eventually spreading. Grafting is a process in which a disease resistant rootstock is grafted to a second variety that lacks the disease resistance but produces the desired fruit. TBRFV has just recently been identified as an important tomato pest, but is still mostly isolated to parts of southern Europe, Mexico, and most recently California. It’s possible for growers to make their own grafted plants, and several seed companies sell seed of disease resistant rootstocks. Several seed/plant companies also sell finished grafted plants. and bio-pesticides should be addressed on priority basis to make the The disease spreads by water droplets that carry spores, either from the soil to the plant, or from older diseased leaves to younger leaves/stems on the same plant or from an adjacent plant.

Some states recommend specific IPM programs for tomatoes 4. Disease movement from the soil to the plant can be greatly reduced by mulching. This is true for both open field and protected culture. As a rule of thumb tomato plants should be watered from the base of the plant, not as an overhead sprinkling, as to avoid pathogen spore distribution through water drops. This does not apply when plants are grown in containers in greenhouses/high tunnel production and new media is used every year. Fusarium wilt) there are multiple races of the pathogen, and multiple disease resistance genes may be necessary to control all races.
