Procure 50WS fungicide, from Crompton/Uniroyal Chemical, is now registered in Arizona for control of powdery mildew on cucurbits (including watermelons and muskmelons, cucumbers, pumpkins and squash), plus in strawberries, grapes, pome fruit and cherries.
The active ingredient in Procure is triflumizole, the only fungicide currently approved for protection of cucurbits and other crops based on imidazole chemistry. Unique imidazole chemistry offers an excellent resistance management tool to Arizona growers who are now experiencing declining performance from registered powdery mildew products. Procure can be used as a tank-mix or rotation partner in a season-long powdery mildew control program.
Triflumizole is effective in inhibiting ergosterol biosynthesis in fungi. Many of the higher fungi, like the powdery mildews, must synthesize ergosterol as a stabilizer for the membranes that make up their cell walls. Therefore, if the fungi are prevented from forming cell walls, the organism collapses and dies.
Procure possesses translaminar and vapor action activities providing control of powdery mildew on upper and lower leaf surfaces. Its unique mode of action also offers both protective and eradicant properties against powdery mildew by inhibiting the spread of disease within the plant, and by preventing sporulation.
Other important features of Procure include: Flexibility in application timing; user-friendly “Caution” signal word; rainfast in 1 to 2 hours; minimal personal protective equipment (PPE consists of long-sleeved shirt and long pants, chemical-resistant gloves made of any waterproof material, shoes plus socks); 12-Hour Restricted Entry Interval (REI) and short pre-harvest intervals (PHI's) from zero to 14 days.
See label directions for crop specific use rate recommendations and use higher rates and shorter spray intervals where disease pressure is high.
Procure 50WS is a wettable powder packaged in convenient, easy-to-use water-soluble pouches. It is compatible with commonly used pesticides registered for use on the recommended crops in an integrated pest management strategy. It is known to provide complete crop safety and no reported adverse plant growth regulating activity at recommended rates.
