Bacterial Spot, Speck, and Canker Small, dark spots on foliage and fruit. Blossom End Rot Firm, sunken area on blossom end of fruit. Actigard WG oz 4 8 app Actigard is a plant resistance activator. Under certain conditions, this product may lead to reductions in yield. Refer to label for disclaimer. Begin applications within week of transplanting. Make up to 8 applications, at weekly intervals. After the eighth application, switch to copper sprays if bacterial diseases are present. Begin Actigard applications at.33 oz/a, increasing to. oz/a as plants grow. fixed copper + mancozeb 8WP AgriPhage calcium chloride See label. lb pt 22.4 lb Ridomil/ Copper can be used, but see label for limitations on use of Ridomil. Adding Tanos to copper and mancozeb may slightly enhance efficacy. May be useful where copper-resistant bacterial strains are present. Cannot be tank-mixed with copper. Use as part of cooperative program with Omni-Lytics, ( ), who formulates the bacteriophage to match your bacterial strains. Re-sample frequently, to accommodate strain shifts. 4 lb/ gal 4 app Apply as soon as problem is detected or earlier. Maintain adequate calcium level in soil and uniform soil moisture. Avoid excessive irrigation when plants are small. 2

14 Pest TOMATO, FIELD Early Blight Brown target spots followed by blighting of foliage. Late Blight (also see late blight, below) Dark, irregular spots, often worse on younger leaves. Favored by mild, wet weather. Anthracnose Circular, sunken spots on ripe fruit. Septoria Leaf Spot Small, gray circular leaf spots with dark borders. Fusarium Wilt Yellowing and wilting of foliage.

Notes for Quadris: Do not apply until 2 days after transplanting. Alternate with a non-related fungicide. Do not mix with an adjuvant. Use higher rate when late blight is present. Notes for Cabrio: See label for precautions on tank mixes. Use higher rate only when late blight is a threat, and alternate with a nonstrobilurin fungicide. Notes for late blight: Most strains are resistant to Ridomil. Control of late blight by chlorothalonil, mancozeb, or maneb can be improved by using high pressure sprays and by adding fixed copper. The late blight fungus can overwinter in potato tubers and in greenhouse tomato plants. Notes for Tanos: Must be tank mixed with and alternated with a non- Group fungicide such as chlorothalonil, mancozeb, or copper..

Southern Blight Plants wilt and die. White mold can often be seen on base of stem. Verticillium Wilt Yellowing of leaves; inside of main stem has tan discoloration. Terraclor WP (soil treatment) 3 lb/ gal water The Endura tomato label does not include this disease; however, applied as for early blight control, Endura should provide suppression of Sclerotinia. Turn soil deep to bury plant debris which might harbor disease organisms. Use Terraclor in setting water ½ pt per plant.. Rotate with sod crops. Crop rotation, fumigation, and resistant varieties are treatments.

After the peak of production, the watering rate may be reduced. b The gallons of water/a/week is based on 2,6 gallons of water/a inch and 2 ft wide beds on 6 ft centers. Therefore, only /3 of the soil area is receiving water (2 ft out of 6 ft).
