Abstract
In field trials from 1978-80, various cropping systems, which involved competitive crops, selective herbicides, fallow periods and tillage, were evaluated for the control of C. esculentus. Tuber populations were reduced 98-99% within 3 yr by the following regimes: (a) cultivation of cotton for 2 yr with pre-sowing application of fluridone or with 2 hoeings/yr, followed by cotton treated with DSMA and MSMA, (b) barley followed by dry- or wet-fallow plus tillage for 2 yr with cotton in the 3rd yr, (c) double-cropping potatoes treated with EPTC with soyabeans treated with alachlor for 2 yr followed by cotton. A 97% reduction of weed tubers in 3 yr was obtained by double-cropping potato with Sorghum bicolor for 2 yr before growing cotton. The relative merits of the systems are discussed
