Description
Mode of action
Fluroxypyr-methyl belongs to the chemical class of pyridyloxyacetic acid derivatives and acts as a highly effective systemic herbicide of the auxin type.
The active substance is rapidly absorbed by weed leaves and translocated throughout the entire plant, including the root system, ensuring complete destruction even of persistent species.
The mechanism of action is based on disrupting the plant's hormonal balance, leading to uncontrolled cell growth and subsequent tissue necrosis.
The first visual symptoms of damage, such as leaf curling and stem deformation, appear within hours after the application of the preparation.
Complete mortality of susceptible weeds typically occurs within 2–3 weeks depending on environmental conditions and the developmental stage of the plants.
What it targets
The primary use of fluroxypyr-methyl is for controlling a wide spectrum of annual and certain perennial broad-leaved weeds in cereal crops.
It is particularly effective against such problematic species as cleavers (Galium aparine), field bindweed, common chickweed, and various knotweed species.
The substance successfully suppresses weeds that exhibit resistance to other herbicide types, such as those based on 2,4-D or MCPA.
The herbicide is also applied on corn, onions, turf, and pastures where selective elimination of broad-leaved vegetation is required without harming the cereal crops.
Its effectiveness is maintained even when used in tank mixtures, which allows for broadening the spectrum of controlled harmful targets.
Rates and timing
The application rates of fluroxypyr-methyl vary depending on the weed species composition, their growth stage, and the specific crop being treated.
The optimal time for application is during the period of active weed growth, ideally when plants are at the 2 to 6 true leaf stage.
The preparation shows high selectivity and can be applied within a wide window, from the tillering stage to the stem elongation of cereal crops.
When used in intensive protection programs, it is recommended to strictly follow the regulations provided by the manufacturer for each specific product.
Ensuring uniform coverage of the leaf surface with the spray solution is crucial for achieving maximum biological efficiency of the herbicide.
Restrictions
When working with fluroxypyr-methyl, it is essential to prevent drift of the spray solution onto neighboring fields containing sensitive crops like sugar beets, sunflowers, or vegetables.
Application is not recommended during frosts or extreme drought, as these conditions reduce the weeds' ability to absorb the active substance.
The product possesses no residual soil activity affecting subsequent crops in the rotation, making it safe for most agricultural plants.
Personal hygiene rules must be strictly observed when preparing solutions and utilizing personal protective equipment to avoid contact with skin and mucous membranes.
Storage should be carried out in specialized warehouse facilities at the temperature recommended by the manufacturer to maintain the stability of chemical properties.
