Jassid resistance in the cotton plant

May, A. W. S. (1951) Jassid resistance in the cotton plant. Queensland Journal of Agricultural Science, 8 (4). pp. 43-68.



Terminal injury by jassids, expressed as grades of plant reaction, can be related to the nymphal population, irrespective of variety and state of growth of the crop. This association enables a determination of varietal susceptibility based on injury symptoms. For each variety, susceptibility to jassid attack can be expressed as a plant resistance index. The method of sampling populations and the various grades of plant reaction recognised from normality to the extreme of jassid damage are described.
