PPP Florida Plant Disease Management Guide: Control Guide for Diseases of Vegetables, Revision No Gary Vallad, Ken Pernezny, Natalia Peres, Richard Raid, Pam Roberts, Shouan Zhang 2 This publication is a guide to lawful use of sprayable chemicals intended for control of plant diseases affecting vegetables grown in Florida. For each crop, products are listed by FRAC code in alphabetical order to help differentiate products based on their active ingredient(s) and their specific mode of action(s). Control of plant diseases is achieved by utilizing numerous cultural, biological, regulatory and chemical tactics. This publication serves as a guide to chemical control for vegetables grown in Florida. The performance of a chemical is enhanced by utilizing non-chemical tactics to reduce inocula. Also, within chemical control, numerous variables influence the performance of the chemical. Time of applications, nozzle arrangement, spray dilution, chemical rate per unit area, adjuvants, and rainfall are some of the variables associated with chemical application technology. Beginning spray programs prior to or at first sign of disease is best. USE A SPRAY ADJUVANT WITH A SPREADER AND A STICKER IN CONJUNCTION WITH SOME WETTABLE POWDER AND SOME FLOWABLE FORMULATIONS. SPREADER-STICKER ADJUVANTS ARE USEFUL PARTICULARLY ON SLICK LEAF AND VERTICALLY LEAF-ORIENTED CROPS LIKE ONIONS, CRUCIFERS AND SWEET CORN. SEE PLANT PROTECTION POINTER NO. 37 FOR MORE DETAILS ON ADJUVANTS. DO NOT USE SPRAY ADJUVANTS IF THE LABEL INDICATES THAT ADJUVANTS SHOULD NOT BE USED. SEVERAL LABELS INDICATE THAT ONE SHOULD NOT USE SILICON ADJUVANTS WITH THOSE PRODUCTS. 1.

2 Archival copy: for current recommendations see or your local extension office Florida Plant Disease Management Guide: Control Guide for Diseases of... 2 The purpose of this listing is to guide you with legal use of sprayable plant disease control chemicals. All legally available, plant disease control chemicals sold in Florida are not listed. For such a listing contact the Florida Department of Agriculture. s listed in this guide are 1) those for which data from Florida are available for the active ingredient, 2) those for which no other compound(s) is known to be available, but is legal for use (tolerance established and labeled) utilizing performance data from the United States, 3) those which are legal to use and lack data from Florida but would be expected to perform satisfactorily based upon professional judgement. It may seem rhetorical but read the label; you paid for it. Read labels for information about crop rotational limitations with fungicides. Also note within this publication the crop groupings for tolerance establishment that are available. REENTRY into fields treated with any pesticide is restricted by the use of a time interval, type of clothing to be worn, or protective wear needed. For example, labels of products containing chlorothalonil allow for a 12 hour reentry interval. However, if adequate eye protection is not provided, the reentry interval is extended to 7 days. Label information supersedes all other sources of information. If the label does not specifically prohibit greenhouse use, the material can be used in the greenhouse. For the full pdf guide go to Rotate unrelated chemicals in your spray program for resistance management. Continued use of the same or related chemicals can result in insensitivity (resistance) of the target pest to that chemical or others in the same group. To assist, chemicals are listed by FRAC code in alphabetical order to help distinguish the fungicide mode of action. All fungicides within the same group (with same number or letter) indicate same active ingredient or similar mode of action. ALL STROBILURIN FUNGICIDES ARE IN GROUP 11 AS INDICATED ON THEIR LABELS AND THEY SHOULD NOT BE ROTATED WITH EACH OTHER. GROUP 11 INCLUDES: FLINT, QUADRIS, QUADRIS OPTI, AMISTAR, HEADLINE, CABRIO, & PRISTINE.
