DB—Lancaster Farming. Saturday, February 14,1981 Tomato diseases cost Pa. growers |$ HERSHEY Bacterial speck and early blight are among the three most costly diseases of tomatoes in Pennsylvania, ac cording to Alan A Mac Nab, of Penn State. Anthracnose fruit rot is the other major disease on processmg tomatoes Bacterial speck symptoms, caused by the bacterium Pseudomonas synngae pv. tomato, include tiny raised black specks on green and ripe fruit, and small dark spots associated with tom areas on leaves .Fruit symp toms result in serious grade reductions in fresh market tomatoes and green wraps, and are a problem in whole-pack processmg tomatoes because the specks frequently can not be removed with the skin. Bacterial speck is promoted by cool weather, relative humidity of at least 80 percent, a long dew period, blowing and splashing ram, and continuous culture of tomatoes. The disease organism is thought to survive on seed, and overwinter in soil for one year. Early blight, caused by the fungus Altemana solam, is the most important defoliation disease of tomatoes. It is characterized by numerous 1/4- to 1/2-inch diameter Switch fertilizer tanks to a Calumet vacuum tank with soil injector Liquid hog manure can save thousands of dollars in commercial fertilizer costs. So it makes sense to preserve that value with good management. That’s why Calumet recommends pairing our vacuum tank with a 2 or 4-shank Calumet soil injector. Soil plow down retains about four times the nitrogen lost with surface spreading, plus reduces odor and runoff Stop in to see the full line of Calumet vacuum tanks in capacities from 1180 to 4500 gallons and choice of two vacuum pumps And ask about the benefits of using a Calumet 2 or 4-shank soil injector tv-..

Yield reductions of over 50 percent have occurred where disease is prevalent and control is not attempted Early blight is promoted by long periods of high relative humidity (above 90 percent RH for 60 or more hours within 5 days), moderate to heavy rainfall (1 or more inches in 7 days), long leaf wetness periods from ram or dew, and moderate temperatures when leaves are wet (69 to 77 degrees Fahrenheit is optimum). Controls include rotation, use of disease-free transplants produced from hot-water treated seed in pathogen-free soil, and use of appropriate fungicide programs, said Mac Nab Speck has been controlled consistently by a tank mixture of maneb plus fixed copper where applications were made weekly and coverage was good, he pomted out Early blight is controlled by regular applications of Bravo, Difolantan, maneb, Polyram, and zinc-iron maneb.
