Title Physiological Studies on Foliar Diseases: Varietal Differences in Response to Use of Fungicides
 
Creator Williams, J H

Subject Groundnut
 
Description Physiological effects of Puccinia arachidis causing rust, and Phaeoisariopsis personata causing late leafspot on yield achievement in groundnut have been investigated. The relationship between green leaf area remaining at maturity and yield was linear in most genotypes investigated. Yield response to fungicide application varied with genotype. Generally, the control of the diseases resulted in small increases in yield in resistant types and larger increases in susceptible types. However, for some resistant genotypes certain fungicides could greatly increase yield without greatly influencing green leaf area. Of the germplasm accessions tested, no line combined resistance to the two diseases with high yield potential.
