Usage

Description

Trifloxysulfuron-sodium, also known as CGA 362622, is a post-emergence herbicide that was commercialized by Syngenta in 2001. It is a white solid with effective properties for controlling various types of weeds in agricultural fields.

Uses

Used in Agricultural Industry:
Trifloxysulfuron-sodium is used as a herbicide for controlling a wide range of weeds in cotton and sugarcane production areas. It is effective against weeds such as Acanthospermum hispidum, A. artemisiifolia, Bidens bipinnata, B. pilosa, Cassia album, C. occidentalis, Desmodium tortuosum, Eupatorium cappilliforium, Euphorbia heterophylla, Gnaphalium pensylvanicum, Ipomoea spp., Linaia canadensis, Melochia corchorifolia, Mollugo vertillata, Panicum adspersum, Rottboellia cochinchinensis, Senna obtusifolia, S. exaltata, Trianthema portulacastrum, and X. strumarium.
In cotton, it is formulated as a WG 75 and can be applied post-emergent at 5–7.5 g a.i. ha?1 in conventional or GM cotton, but at higher rates of 10–15 g a.i. ha?1 if post-emergent directed. The application of trifloxysulfuron-sodium may be made after cotton (picker-type varieties only) has reached a minimum of five true leaves, with applications continuing until 60 days before harvest.
For cotton and sugarcane, trifloxysulfuron-sodium is marketed under the trade name "Envoke" as a straight product. In cotton, it is used in combination with prometryn as "Suprend," and in sugarcane in combination with ametryn as "Krismat." In sugarcane, "Envoke" can be used for a maximum of three applications prespiking, post-emergence over the top, and/or post-emergence directed at a total rate of 78 g a.i. ha?1 per season. The product may be applied to sugarcane at a plant height of 45–60 cm up to 100 days before harvest. At a dose rate of 16 g a.i. ha?1, the following weeds are controlled with greater than 85% efficacy: Alternanthera philoxeroides, A. hispidum, Panicum adspersum, M. vertillata, X. strumarium, C. occidentalis, Gnaphalium pensylvanicum, Eupatorium cappilliforium, Desmodium tortuosum, T. portulacastrum, S. exaltata, Rottboellia cochinchinensis, C. album, Ipomoea spp., C. esculentus, C. rotundus, Amaranthus spp., A. artemisiifolia, M. corchorifolia, S. obtusifolia, Bidens bipinnata, Linaia canadensis, A. theophrasti, and E. heterophylla.
