Gamma EC

Chemical Mechanism: Selective Weed Control

"Gamma EC" utilizes Quizalofop-P-ethyl, a member of the aryloxyphenoxypropionate class, as its active ingredient. Unlike contact herbicides, this systemic agent is absorbed through the leaf surface and translocates via the phloem and xylem directly to the growth points and rhizomes. This is essential for controlling perennial grasses like quackgrass (Elymus repens), where root destruction is mandatory for complete eradication.

Technical Specifications and Application

The formulation as an Emulsifiable Concentrate (EC) by Nanjing No.1 Pesticide Factory (Red Sun Group) ensures superior adherence to the waxy cuticle of grasses. By inhibiting lipid synthesis, the herbicide effectively shuts down the metabolic pathways unique to monocotyledonous weeds while remaining non-toxic to broad-leaved crops such as sugar beet, sunflower, soybean, and flax.

• Systemic Efficacy: Rapid movement within the plant leads to growth cessation within 24–48 hours post-application.
• Flexibility: Can be applied at varying growth stages, from the 2-leaf stage through tillering, with application rates ranging from 1.0 to 3.0 L/ha.
• Safety Profile: Classified as Class 3 hazard, with a 1-day pre-harvest/pre-entry interval, making it a highly practical choice for integrated pest management.

The manufacturing process at the Nanjing facility ensures consistent emulsion stability, which is vital for maintaining a uniform concentration in the sprayer tank. Distributed in collaboration with Clov and Green Express, the product is optimized for diverse agricultural conditions, providing a reliable solution for selective grass control in row crops.
