Valent U.S.A. Corp. has received California state registration for Presidio fungicide in brassica (head and stem), bulb and root vegetable crops (except carrots, potatoes and sugar beets). The fungicide is currently registered on these crops in most states; New York registration is pending.



Available across a number of vegetables, Presidio's breakthrough, targeted chemistry has proven highly effective for growers with crops threatened by downy mildews. Presidio also controls Phytophthora root rot.



"This new registration brings Presidio's fast-acting chemistry and two-day pre-harvest interval to California brassica, bulb and root vegetable growers struggling with downy mildew and Phytophthora," said Rick Kraus, product manager. "And Presidio's novel mode of action brings these growers a powerful tool to incorporate into their pest management programs and help ward off resistance concerns."



Unlike other fungicide products, Presidio has no known tank mix limitations with other fungicides or insecticides. Presidio can be applied via sprinkler or used as a foliar treatment.



Valent has also received California registration for the use of Quash fungicide on stone fruit and tree nuts. Quash currently is registered in a number of states; registration is pending in New York.



Quash is a new, highly effective, broad-spectrum triazole fungicide containing metconazole, a new active ingredient for tree nuts and stone fruit. Quash offers excellent control of such diseases as blossom blight, Alternaria leaf spot, shot hole, scab, brown rot and more. Trials show that Quash results in improved tree nut and stone fruit quality, greater yields and an excellent return on the grower's investment.



"We believe growers will see a significant value from Quash fungicide," said Gerald Holmes, Valent product development manager. "Quash has been a top-performing fungicide in many University of California research trials as well as in demonstration trials in California and throughout the country."



In university trials, Quash has shown consistent top-rated control of brown rot, blossom blight and other key diseases with preventive and curative action.



"Triazole chemistry keeps improving, and Quash is an excellent example of new generation efficacy," said Holmes. "Quash offers growers superior activity on a broad spectrum of pathogens at very low rates."



Additionally Quash offers growers tank mix and timing flexibility and short pre-harvest intervals (14 days for stone fruit and 25 days for tree nuts), and it is also rainfast in two hours.
