%X Molinate controlled red rice (Oryza sativa) in commercial rice (O. sativa cv. Starbonnet) giving an increasing response at rates of 3.6, 4.3, 5.0, 5.7, 6.4, 7.2, 7.9 kg a.i./ha in 1 summer and 2 winter crops. No crop injury was observed at any rate of molinate, and grain yield, grain moisture, 1000-grain weight, head counts, grain number per head, germination counts, percentage bran and head yield were not affected. In 2 experiments, the percentage of whole grain was not affected by the chemical but in 1 experiment percentage whole grain increased with the rate of chemical used. Molinate provides a substantial level of control of red rice in commercial rice but the response to the herbicide is variable. In some crops weed suppression up to about 50% control is all that can be achieved, but in other crops controls of >90% are achievable. With the low levels of infestation that usually occur in North Queensland these levels of control are acceptable.
