Fluazifop-p-butyl is a post-emergence product and provides
excellent control of annual and perennial grasses, including wild
oat and volunteer cereals. Fluazifop-p-butyl is non-toxic to broadleaf
plants and is therefore registered for use in a variety of broadleaf crops,
such as soybean, oilseed rape, sugar beet, fodder beet, potatoes,
vegetables, cotton, pome fruit, stone fruit, bush fruit, citrus fruit, vines,
pineapples, bananas, strawberries, sunowers, alfalfa, ornamentals, and
other broadleaf crops. Application rate ranges from 125-375 g ai/ha.
Mode of Action
Plant Uptake Fluazifop-P-butyl is quickly absorbed into the leaf
surface, hydrolysed to uazifop-P and translocated through the
phloem and xylem, accumulating in the rhizomes and stolons of perennial grasses and the meristems of annual and perennial grasses.
Symptoms Weeds treated with uazifop-p-butyl stop growing within
a few hours, show gradual discoloration on newer growth in 3 to 4
days, and eventually necrosis, desiccation, and plant death occurs
within 2 to 3 weeks.
Selectivity Fluazifop-p-butyl inhibits acetyl CoA carboxylase
(ACCase), which is an essential plant enzyme that acts in fatty acid
synthesis, and selectivity due to the difference of the enzyme sensitivity between gramineae and non-gramineae plants.
