Abstract: Jigu 35 using as the test plant material,12.5% sethoxydim EC,10% monosulfuron WP, 5% imazethapyr WA,56%MCPA sodium WP four kinds of commonly used herbicides were sprayed on cereal leaves. Setting low,medium and high levels,soil-applied herbicide and stem and leaf treatment,the efficiency of foxtail miller seedling for anti-screening test was conducted.Results showed that leaf spraying of 5% imazethapyr 2.0 kg/hm^2（dosage of active ingredients） dosage was good inhibition to the gramineous weeds with 4-6 leaves and it was safe to spring wheat and leaf spraying of 5% imazethapyr 3.0 kg/hm^2（dosage of active ingredients） dosage was good inhibition to the broad-leaved with 4-6 leaves and it was safe to spring wheat.
