What is cyhalofop-butyl and how should it be used?
What is cyhalofop-butyl? How is cyhalofop-butyl used? We ask knowledgeable netizens to help explain. Currently, the agricultural input market has cyhalofop-butyl herbicides in 10%, 15% or 100g/L emulsifiable concentrate formulations, but some farmers do not understand how to use cyhalofop-butyl herbicide, so Zhongdiwang has compiled the principles and usage of cyhalofop-butyl herbicide...
What is cyhalofop-butyl? How is cyhalofop-butyl used? We ask knowledgeable netizens to help explainCurrently, the agricultural input market has cyhalofop-butyl herbicides in 10%, 15% or 100g/L emulsifiable concentrate formulations, but some farmers do not understand how to use cyhalofop-butyl herbicide, so Zhongdiwang has compiled the principles and usage of cyhalofop-butyl herbicide, listed in detail below for netizens' reference.
The herbicidal principle of cyhalofop-butyl herbicide:
Cyhalofop-butyl herbicide belongs to the aryloxyphenoxypropionate class of low-toxicity herbicides; cyhalofop-butyl herbicide is a highly efficient selective systemic conductive stem and leaf treatment agent, absorbed through plant leaves and leaf sheaths, mainly inhibiting the formation of acetyl-CoA carboxylase in weeds, so that fatty acid synthesis is inhibited and weed cells cannot divide normally. It is relatively safe for rice. Cyhalofop-butyl herbicide is suitable for controlling annual grass weeds such as barnyardgrass and Chinese sprangletop in paddy fields, but it is ineffective against broadleaf weeds.
However, from the absorption of cyhalofop-butyl to the death of weeds, it is relatively slow, generally requiring 1-3 weeks.
Methods of using cyhalofop-butyl herbicide in paddy fields:
At the 3 to 5 leaf stage of rice seedlings (weeds: barnyardgrass and Chinese sprangletop at the 2 to 4 leaf stage), use 50-75 milliliters of 10% cyhalofop-butyl emulsifiable concentrate per mu, dilute with 30-40 kilograms of water, and spray on weed stems and leaves.
Precautions for using cyhalofop-butyl herbicide:
Note 1,When applying cyhalofop-butyl herbicide, the water layer in the paddy field should preferably be lower than 1 cm or drained, as this gives the best effect; after application, the field can be re-irrigated 2 days later.
Note 2, Cyhalofop-butyl herbicide mixed with some herbicides for controlling broadleaf weeds, such as MCPA, sulfonylureas or bentazone, will produce antagonism and reduce efficacy. Therefore, if other broadleaf weeds and Cyperaceae weeds need to be controlled, it is best to apply other herbicides 7 days after applying cyhalofop-butyl herbicide.
Note 3, 10% cyhalofop-butyl emulsifiable concentrate should be used at most 1 time against weeds such as barnyardgrass and Chinese sprangletop in rice.
