SUMMARY Applications of cellulose xanthate equivalent to 25 kg cellulose/ha increased the numbers of weed seedlings by up to 23% compared with untreated controls. With propachlor and prynachlor, weed control was poorer in the presence of cellulose xanthate and analyses of soil samples demonstrated that the rate of herbicide loss from the soil was enhanced. Although the soil conditioner increased the rate of loss of some other acetanilide herbicides, weed control was not greatly affected. The results suggest that interactions between cellulose xanthate and acetanilide herbicides are only important with those compounds which are normally of very short persistence.
