Effects of climate change on productivity of agricultural crops in relation to diseases that attack them are difficult to predict because they are complex and nonlinear. To investigate these crop-disease-climate interactions, UKCIP02 scenarios predicting UK temperature and rainfall under high- and low-CO(2) emission scenarios for the 2020s and 2050s were combined with a crop-simulation model pr...

Phytophthora pathogens are responsible for some of the most serious diseases of cocoa including phytophthora pod rot (PPR) or black pod, stem canker, leaf and seedling blight, chupon wilt and flower cushion infections. PPR causes 10–30% annual losses in production of cocoa beans globally, and much higher losses locally in particularly wet and humid conditions. Stem canker causes further losses ...

Some of the factors that influence canker development in American sycamores inoculated with Botryodiplodia theobromae conidia were determined. A combination of B. theobromae culture filtrates and conidia resulted in 100% canker production when Iiitroduced into stem wounds; however. a combination of Cephalosporium diospyri culture filtrates and B. theobromae conidia resulted in no canker product...

Pitch canker, caused by the fungus Gibberella circinata (anamorph = Fusarium circinatum), was first identified in 1945 as a disease of pines in North Carolina (7). Pitch canker now occurs throughout the southeastern United States where it remains a chronic problem in plantations, nurseries, and seed orchards (2,3). In California, a pitch canker infestation that was first recognized in 1986 has ...

Shallow bark canker incited by Brenneria nigrifluens is considered one of the most dangerous diseases which can cause a significant reduction in walnut and timber production.  During spring and summer of 2019, walnut gardens were surveyed for symptoms like leaf spot, fruit, and stem canker from four different regions of Golestan province located in Iran. A set of 11 Gram-negative bacteria were ...

Leptosphaeria maculans and L. biglobosa are closely related sibling fungal pathogens that cause phoma leaf spotting, stem canker (blackleg) and stem necrosis of oilseed rape (Brassica napus). The disease is distributed worldwide, and it is one of the main causes of considerable decrease in seed yield and quality. Information about the time of ascospore release at a particular location provides ...

Pitch canker disease (Fusarium circinatum Nirenberg & O'Donnell) causes serious shoot dieback, reduced growth and mortality in pines found in the southern and western USA, and has been linked to nutrient imbalances. Poultry houses with forced-air ventilation systems produce nitrogen (N) emissions. This study analyzed spatial correlations between pitch canker disease and foliar, forest floor, so...
