Relative Efficacy of Simazine and Select Dithiolcarbamates in the Control of Weeds in Hybrid Sorghum

Abstract

Sorghum is grown on comparatively heavier soils on which control of weeds is one of the most difficult tasks as these soils and climatic conditions give rise to a host of weed problem. Past experiments at Udaipur showed that application of 2, 4-D sodium salt best controls weeds when applied at the rate of 1.0 to 1.5 kg/ha (Singh and Faroda, 1964). Yet, some weeds like Trianthema portulacustrum and Physalis minima remained unhurt and hand weeding was the best to control many of the weeds including Trianthema portulacustrum (Singh and Porwal, 1967). Use of simazine which has given remarkable control of weeds in maize and also other herbicides as EPTC and PEBC which hold great promise are worth trying. Since time and rates of application of these herbicides are different for different crop weed situation it will be of practical importance to try these new herbicides and work out proper time and rate of application and to see how the new practices compare with the traditional methods of controlling weeds by the use of 2, 4-D.
