Sedumo Protect

Technical capacity of "Sedumo Protect": how quizalofop-P-ethyl works

The product is based on a classic solution from the aryloxyphenoxypropionate group — quizalofop-P-ethyl. This systemic herbicide is valued in agronomy for its narrow specialization and high rate of penetration into the weed metabolic system. Its function is to block the acetyl-CoA carboxylase enzyme, which completely halts fatty acid synthesis at the growth points of grass weeds.

Mechanism of selectivity and systemic action

The main technological component of this herbicide's action is its selectivity. Thanks to its emulsifiable concentrate formula, the product is rapidly absorbed by the leaf surface and moves through the phloem directly to the root system and nodes within a few hours. An important nuance: the product works exclusively against grass flora, leaving dicotyledonous crops (beet, rapeseed, soy, sunflower) unaffected. This biological "filtration" makes it a post-emergence safety tool applied to actively growing weeds.

Targeted weeds

• Perennial rhizomatous weeds: couch grass (Elymus repens).
• Annual grasses: green and yellow foxtail, wild oats, common barnyard grass, silky bentgrass.

Application is post-emergence/foliar. Since the active substance is systemic, the weed growth stage is critical (the best results are achieved at the 2–4 true leaf stage for annual grasses and at a height of 10–15 cm for couch grass). The product from Hangzhou Ruijiang Chemical Co., Ltd. requires strict adherence to the application rate of 0.4 to 1.2 L/ha depending on the weed infestation level, with a maximum of one application per season.
