Arysta’s graminicides provide option to prevent new weed resistance
Nov. 22, 2016
Arysta LifeScience has broad experience in graminicides based on two different molecules, which allows the company to offer Rango GR (quizalofop-p-tefuryl) and Lord 24 (clethodim). Meanwhile, the company is planning new launches for greater sustainability in weed control technologies in Argentina.
Rango GR behaves as an excellent option to rotate modes of action and prevent the generation of new weed resistance.
Some years ago, technicians began discuss on resistant or tolerant weed species in different areas of Argentina. The progress in resistance was due to the selection exerted in the population of plants, due to the repeated use of the same herbicide or different herbicides with the same mechanism of action.
The proper management of this type of weeds includes not only crop rotations, and in some cases cultural controls, but also the use and rotation of different modes of action, such as in graminicides. Rango GR is a post-emergent graminicide for the control of annual and perennial grasses in crops such as soy, peanut and sunflower. Its active ingredient is quizalofop-p-tefuryl, at a concentration of 12%, which is an efficient weed control tool that is resistant to glyphosate and is indispensable in different strategies to combat proliferation of these difficult-to-control species.
Like all graminicides, Rango GR should be applied in combination with an agricultural oil containing a suitable concentration of emulsifiers in its formulation, in the style of Metyloil Line. This will ensure rapid penetration of the graminicide into the plant and an accelerated translocation to the growth points, causing rapid death of weeds.
