BROMACIL 80 WP

INTRODUCTION: Bromacil 80 WP is an organic compound a residual uracil herbicide effective against a wide range of both perennial and annual broad- leaved weeds and grasses. It can be used for total weed control on non-crop land at 8.0-10.0 Kg/hectare, or for selective weed control in cropped-land situations at 1.0-4.0 Kg/hectare. It is particularly suitable for use in plantation crop situations eg citrus and pineapples. Bromacil 80 WP is mainly applied prior to weed emergence in crops and plantations or as a soil sterilant in non-crop areas. It needs activation by rain or irrigatation. Combinations of Bromacil with contact herbicides will effectively control established weeds and prevent the emergence of new weeds. Bromacil 80 WP is used primarily for the control of annual and perennial grasses and broadleaf weeds, both non-selectively on non- crop lands and selectively for weed control in a few crops (citrus and pineapple). It appears to act in plants by inhibiting photosynthesis and to be primarily absorbed through the roots. At higher use rates its effects usually persist for more than one growing season. Care must therefore be taken when planning sequential crop rotations on the same land for the season following treatment with Bromacil 80 WP. Total weed and brush control on non-crop land; and selective control of annual and perennial weeds and grasses in citrus and pineapple plantations. Bromacil 80 WP can be used for selective control of annual and perennial weeds in orange, grapefruit, and lemon orchards.

Mode of Action: Bromacil is mainly absorbed via the root systems and also partially through foliage and stems in the case of young seedlings. Bromacil requires rainfall or irrigation to ensure that it penetrates to the root zone and so may be taken up. Uptake is primarily via the xylem and the toxic action relies upon inhibition of photosynthetic electron transport pathway at the photosystem II receptor site. This results in the impairment of photosynthesis.
