Some farmers in the dry land due to improper use of acetochlor method caused poor herbicidal effect, and even caused phytotoxicity. To this end, the author suggests that the following four points should be noted when using acetochlor in dryland.
Soil moisture A certain soil moisture is conducive to improving the herbicidal effect. For example, when the treatment is in continuous dry weather, the herbicidal effect will be greatly reduced. Therefore, first watering to increase soil moisture and then use it is one of the key measures to improve the efficacy of acetochlor.
Time of administration Acetochlor is a selective pre-emergence herbicide. Only when the weeds are used before the crops are planted, can the effects be achieved, and the earlier the better, the better. For the weeds that have been unearthed, acetochlor is basically ineffective.
Land preparation quality The quality of the land preparation is not good, and the old grass is not removed, which will directly affect the weeding effect. In addition, the soil is uneven, and it is impossible to spray the liquid evenly, which also affects the herbicidal effect.
The phytotoxicity problem prohibits the use of acetochlor for weeding in sensitive crops such as cucumber, rice, spinach, wheat, leeks, millet, sorghum, etc. When acetochlor is used for weeding on tomatoes, corn, soybeans, rapeseed and other crops, the amount per acre is limited. 50 ~ 75 ml, otherwise it is easy to produce phytotoxicity.
