Actigard WG.33 -. 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, (866-28- 2644), 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

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.

more water is lost through transpiration. 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). If 2 ft beds were spaced on ft centers, then the gallons required would be % higher. c This is a broadcast rate (the entire acreage, not just the area under the plastic). If calculating on a treated acre (the acre under the plastic), the rate would be 2. - 3 lb N/A/day. d This is a broadcast rate (the entire acreage, not just the area under the plastic). This rate can be applied once a week or split over several applications. e If a soil test is generated, then apply 6 lb/a N and P 2 O and K 2 O according to the soil test recommendations. However, if no soil test is generated, then apply a fertilizer that results in - 6 lb/a N and - 2 lb/a of each P 2 O and K 2 O (-- to 6-2-2).
