FAQ
What is Quizalofop-p-ethyl 5% EC?
Quizalofop-p-ethyl 5% EC is a herbicide that
contains the active ingredient quizalofop-p-ethyl, which belongs to the
aryloxyphenoxypropionate group of herbicides. It is used to control grass weeds in various
crops like soybeans, rice, cotton, peanuts, and corn.
How does Quizalofop-p-ethyl 5%
EC work?
Quizalofop-p-ethyl works by inhibiting the enzyme acetyl coenzyme A
carboxylase (ACCase), which is essential for lipid biosynthesis in plants. This inhibition
disrupts the plant's ability to grow and ultimately leads to its death.
What types of
weeds can Quizalofop-p-ethyl 5% EC control?
Quizalofop-p-ethyl 5% EC is effective in
controlling grass weeds like barnyard grass, goosegrass, crabgrass, foxtail, and signal
grass. It provides selective control, meaning it targets grassy weeds while leaving
broadleaf crops unharmed.
How should Quizalofop-p-ethyl 5% EC be
applied?
Quizalofop-p-ethyl 5% EC should be applied as a post-emergence spray when
the grass weeds are in the early growth stages. It is recommended to use the herbicide in
combination with adjuvants like surfactants to improve efficacy. Proper calibration of
equipment and application timing is crucial for optimal weed control.
What are the
benefits of using Quizalofop-p-ethyl 5% EC?
Quizalofop-p-ethyl 5% EC offers effective
control of grass weeds in a wide range of crops, reducing competition and improving crop
yield. It is easy to apply and has a short residual activity, allowing for quick
re-cropping. Additionally, it has a favorable environmental profile with low toxicity to
non-target organisms.
Are there any precautions to consider when using
Quizalofop-p-ethyl 5% EC?
It is essential to follow the manufacturer's instructions
and recommended application rates to avoid crop injury or insufficient weed control. Care
should be taken to prevent herbicide drift onto neighboring crops or sensitive areas.
Additionally, personal protective equipment should be worn during handling and application
to minimize exposure risks.
Does Quizalofop-p-ethyl 5% EC have any restrictions or
limitations?
Quizalofop-p-ethyl 5% EC should not be used on crops not listed on the
label or during sensitive growth stages of the crop. It is important to adhere to the
pre-harvest interval specified on the label to avoid residues in harvested produce.
Additionally, care should be taken to prevent contamination of water bodies or non-target
areas.
How can Quizalofop-p-ethyl 5% EC be integrated into an overall weed management
program?
Quizalofop-p-ethyl 5% EC can be used in rotation with other herbicides with
different modes of action to prevent weed resistance development. Cultural practices like
crop rotation, tillage, and weed monitoring can also complement the herbicidal control
provided by Quizalofop-p-ethyl. Integrated weed management strategies can help ensure
sustainable weed control practices in the long term.
What is the shelf life of
Quizalofop-p-ethyl 5% EC?
Quizalofop-p-ethyl 5% EC has a shelf life of approximately
two years when stored in a cool, dry place away from extreme temperatures and moisture. It
is important to check the expiration date on the product label and dispose of any expired or
deteriorated herbicide properly.
