A selective systemic graminicide for the effective control of grass weeds in a wide range of crops.
Description
Mechanism of action and selectivity of Queen Star
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.
Technical aspects of application
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.
- Systemic action: Complete cessation of weed growth is observed within a few hours of absorption, with tissue necrosis occurring within 7–10 days.
- Dosage flexibility: Application rates range from 2.0 to 3.0 L/ha and above, allowing for customization based on the specific weed pressure in the field.
- Safety: With a hazard class of 3 and a short pre-harvest interval (only 1 day), the product is technologically convenient for late-season treatments on vegetables, rapeseed, soybeans, and sunflowers.
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 type of action
By type of action
Depending on their ability to move through living tissues, herbicides are divided into contact and systemic. Contact herbicides cause local damage to plant tissue upon contact, which dies or gradually degrades. This action does not always completely destroy the plant; often, its... |

By Mode of Action
Herbicides are divided into two groups according to their mode of action: Non-selective herbicides — intended for the destruction of all plant species. They are applied in agricultural fields during the absence of the main crop (after harvest, before crop emergence, on fallow lan... |

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... |
