TebuStar 3.6L may be applied in a minimum of 10 gallons of spray solution per acre by ground sprayer or in a minimum of 5 gallons of spray solution per acre by aircraft spray equipment. Check equipment calibration frequently. Complete coverage and uniform application are essential for the most effective results, especially when lower spray volumes are applied. If necessary, increase the spray volume per acre for complete crop coverage.
Rhizoctonia pod rot (Virginia and North Carolina only)
FOUR-APPLICATION SPRAY PROGRAM: Apply the specified rate in a preventive spray schedule. See table below in the label for proper timing of applications. Applications of chlorothalonil should be made prior to and following applications of TebuStar 3.6L to discourage development of resistant strains of fungi. For optimum control of foliar diseases such as leaf rust, web blotch, and pepper spot, the lowest label recommended rate of a spray surfactant should be tank-mixed with TebuStar 3.6L.
LEAF SPOT ADVISORY SCHEDULE: For control of soilborne diseases in an advisory schedule, apply TebuStar 3.6L in the first advisory spray in July and continue TebuStar 3.6L applications at 14-day intervals.
Applications after August 15 should be tank mixed with chlorothalonil for resistance management purposes.
GENERAL DIRECTIONS: For optimum control of the specified soilborne diseases, four consecutive applications of TebuStar 3.6L must be made at 14-day intervals.
TebuStar 3.6L may be applied up to 14 days before harvest. Do not feed hay or threshings or allow livestock to graze in treated areas.
TebuStar 3.6L is a sterol demethylation inhibitor (DMI) fungicide. Chlorothalonil may be tank mixed at the rate of 12 ounces of active ingredient with TebuStar 3.6L as a leaf spot resistance management strategy. A spray surfactant is not necessary when TebuStar 3.6L is tank mixed with chlorothalonil. Mixing or alternating TebuStar 3.6L with other DMI fungicides may lead to resistance.
TebuStar 3.6L must be carried by rainfall or irrigation into the root and pod zone for control of root and pod rots caused by Sclerotium rolfsii and Rhizoctonia solani. Drought conditions will decrease the effectiveness of TebuStar 3.6L against the root and pod rots.
Use TebuStar 3.6L in conjunction with cultural practices that are known to reduce the severity of soilborne diseases, such as proper crop rotation practices.
