FAQ
What is Butachlor 60% EW and how does it work?
Butachlor 60% EW is a selective
herbicide used to control annual grasses and certain broadleaf weeds in paddy rice fields.
It works by inhibiting the enzyme acetolactate synthase (ALS), which is essential for the
biosynthesis of branched-chain amino acids in plants. This disruption leads to the death of
susceptible weeds while leaving the rice crop unharmed.
How should Butachlor 60% EW
be applied for optimal efficacy?
Butachlor 60% EW should be applied as a
pre-emergence or early post-emergence treatment. It is recommended to apply the product
uniformly over the soil surface before the weeds germinate or when they are in the early
stages of growth. Adequate moisture is essential for activation of the herbicide, so
application before rainfall or irrigation is ideal.
What are the benefits of using
Butachlor 60% EW in paddy rice fields?
Using Butachlor 60% EW in paddy rice fields
offers several benefits. It effectively controls a wide range of grassy and broadleaf weeds,
allowing the rice crop to thrive without competition. The selective nature of the herbicide
ensures that the rice plants are not harmed, resulting in higher yields. Additionally,
Butachlor 60% EW is easy to apply and provides long-lasting weed control.
Are there
any precautions that need to be taken when using Butachlor 60% EW?
Yes, several
precautions should be taken when using Butachlor 60% EW. It is important to read and follow
the product label instructions carefully to ensure proper application and safety. Users
should wear appropriate protective gear, such as gloves, goggles, and a mask, when handling
the herbicide. It is also recommended to avoid spraying during windy conditions to prevent
drift onto non-target areas.
Can Butachlor 60% EW be tank-mixed with other herbicides
or pesticides?
Yes, Butachlor 60% EW can be tank-mixed with certain herbicides or
pesticides to improve weed control and reduce the risk of resistance development. However,
it is essential to conduct a compatibility test before tank-mixing to ensure that the
products are compatible and will not negatively impact efficacy. Always follow the label
instructions for tank-mixing ratios and application techniques.
What is the
recommended dosage of Butachlor 60% EW for different weed species?
The recommended
dosage of Butachlor 60% EW varies depending on the target weed species and the stage of
growth. For annual grasses, the typical application rate is between 1.5-2.5 liters per
hectare, while for broadleaf weeds, the rate may range from 2-3 liters per hectare. It is
essential to consult the product label for specific dosage recommendations for each weed
species.
How soon after application can rice be planted in fields treated with
Butachlor 60% EW?
Rice can be planted in fields treated with Butachlor 60% EW within
1-3 days after application. The herbicide is quickly absorbed by the soil and does not
persist in the environment, allowing for safe and timely planting of rice crops. However, it
is crucial to follow the waiting period specified on the product label to ensure optimal
results and crop safety.
What is the shelf life of Butachlor 60% EW and how should it
be stored?
The shelf life of Butachlor 60% EW is typically around 2-3 years when
stored in a cool, dry place away from direct sunlight and extreme temperatures. The product
should be kept in its original tightly sealed container to prevent moisture absorption and
contamination. It is important to store the herbicide out of reach of children, pets, and
livestock to avoid accidental ingestion or exposure.
Is Butachlor 60% EW safe for the
environment and non-target organisms?
When used according to the label instructions,
Butachlor 60% EW is considered safe for the environment and non-target organisms. The
herbicide has low toxicity to mammals, birds, and aquatic organisms when applied at the
recommended rates. To minimize environmental impact, avoid overspraying, runoff into water
bodies, and contamination of sensitive areas such as wetlands.
