A selective systemic graminicide for the effective control of grass weeds in a wide range of crops.
The product is based on the active ingredient quizalofop-P-ethyl, a compound from the aryloxyphenoxypropionate group. Unlike non-selective herbicides, this component demonstrates high selectivity, targeting specifically the acetyl-CoA carboxylase (ACCase) enzyme in the meristematic tissues of grass weeds. Due to its systemic nature, the product is rapidly absorbed by the leaf surface and translocated to growth points, blocking lipid synthesis essential for the formation of weed cell membranes.
The emulsifiable concentrate ensures stability of the working solution and optimal adhesion to the leaf surface. When dealing with fields infested by couch grass, wild oats, or foxtail, "Queen Star" acts as a reliable post-emergence tool. It is crucial to note that maximum efficacy is achieved when applied to actively growing weeds, regardless of the crop's growth stage.
Using "Queen Star" from Nanjing Essence Fine-Chemical Co., Ltd. allows for the mitigation of competition from annual and perennial grasses without the risk of phytotoxicity to the target crop, which is critical during its vital growth stages.

By Application Timing
Herbicides are classified according to application timing into pre-emergent and post-emergent herbicides. Pre-emergent herbicides are mostly soil-applied or granular formulations applied before the emergence of crop plants. They are applied either pre-sowing (during pre-sowing cu... |

By application method
Based on the method of application, herbicides are divided into foliar, soil, and root herbicides. Foliar herbicides are applied to vegetative plants and act through their above-ground organs. The main method of application for such preparations is spraying using sprayers or airp... |
