Effect Of Pasture Spraying On Gall Development., V. Nieman

Experimental Summaries - Plant Research

Sprays with low rates of desiccant herbicide just after head emergence has been shown to control development of toxicity in the same year. The trial was conducted to compare the effect of herbicides with different modes of action on control of toxicity and seed set. 85KA65.

The Tolerance Of Cereals To Herbicides., D. G. Bowran

Experimental Summaries - Plant Research

Herbicides affect not only the weeds present in a crop, but also the crop itself. In the absence of weeds, both positive and negative responses to herbicides have been reported in the literature. The negative responses are the most important, especially if yield is decreased below the economic threshold for herbicide use. Factors which are important in determining the level of crop response to a herbicide include the crop species and variety, the timing of the herbicide, the rate of herbicide and the environmental conditions under which the crop is growing.
