Description
Mode of action
Clethodim belongs to the cyclohexanedione chemical class and is a highly selective systemic herbicide with selective action.
The active substance quickly penetrates plant tissues through leaves and stems, moving with the assimilate flow to active growth points — meristematic tissues.
The mechanism of action is based on inhibiting the enzyme acetyl-CoA carboxylase (ACCase), which is critical for lipid synthesis in plant cells.
As a result of impaired fatty acid biosynthesis, cell membranes lose integrity, leading to a complete cessation of weed growth within hours after application.
Clethodim has a high penetration rate, making it resistant to rainfall washout shortly after application.
What it targets
The product is intended for the destruction of a wide spectrum of annual and perennial grass weeds, including the most difficult-to-control species.
The most sensitive species include quackgrass, barnyard grass, foxtail, wild oats, and blackgrass.
The herbicide effectively controls volunteer cereals, which is especially important when grown in rotations involving grain crops.
The product is used in broad-leaved crops that possess high resistance to the action of clethodim and are not damaged when dosed correctly.
- Soybeans, rapeseed, sunflowers, sugar beets, potatoes, flax, onions.
Rates and timing
Application timing depends on the weed development phase: it is optimal to perform the treatment on actively growing plants in the 2 to 6 leaf stage.
Application rates vary depending on the weed species composition and the degree of infestation, as well as weather conditions during the treatment period.
To increase the product's effectiveness, the mandatory use of adjuvants is recommended, which ensure better coverage and permeability of the working solution.
The number of treatments per season is usually limited to one application, but in cases of high infestation, strategy adjustments may be possible.
It is important to ensure that the crop is not in a state of stress (drought, frost), as this can reduce the herbicidal effect.
Restrictions
Clethodim is a highly specialized herbicide and does not affect broad-leaved weeds, which requires the use of tank mixtures if necessary.
It is not recommended to mix the product with broad-leaved herbicides in the same tank, as this often leads to antagonism and reduced efficacy.
When working with the substance, strict safety measures must be followed: use personal protective equipment for skin, eyes, and respiratory organs.
The product poses a certain danger to aquatic organisms, therefore it is strictly forbidden to allow the working solution to enter water bodies or sewage systems.
Storage should be carried out in the original packaging in a cool, dry place out of reach of children and animals, away from food and feed.
