Defoliation, disease, and growth

TL;DR: This work shows how epidemiological principles can explain the evolution of fungicide resistance, and highlights a theoretical framework to address the question of whether mixtures or alternation provide better resistance management, and demonstrates that precisely how spray strategies are compared must be given extremely careful consideration.

TL;DR: It is important to consider that continuous defoliation injury impacts the capacity of the plant to respond to injury and must be further evaluated for ET refinement in future research.

TL;DR: Variation in CBB and its relation to yield between years was influenced by difference in seasonal weather between years and the type of cropping system influenced CBB severity and the amount of loss in yield attributable to CBB.

TL;DR: It is suggested that traditional disease thresholds may be unreliable predictors of the need to spray and that estimating the success of a treatment decision by observing disease levels later in the season is prone to error.

TL;DR: Late infestations of Gaeumannomyces graminis on wheat were monitored using sequential measurements of plants taken from a series of line transects to find photosynthetic potential of the stand was reduced following take-all infection, resulting in a lower total biomass production and a concomitant reduction in grain yield.

TL;DR: The sequentially-branched cultivar, with few initials for vegetative growth, did not give the same increase in leaf growth as the alternate cultivars and was hardly changed by spraying.

TL;DR: Linear relationships between both total and tuber dry-matter yields and the amount of radiation intercepted by potato crops are demonstrated, suggesting that, in the absence of disease and drought, the essential objective in the production of this crop is to maximize radiation interception.
