Control of grey mould, caused by Botrytis spp., is a major challenge in open field strawberry production. was isolated from plant parts collected 19 perennial fields with suspected fungicide resistance the Agder region Norway 2016. Resistance to boscalid, pyraclostrobin and fenhexamid high found 89.1%, 86.0% 65.4% conidia samples, respectively. Multiple common; 69.6% samples exhibited three or ...

Zymoseptoria tritici is the causal agent of Septoria blotch, most important disease affecting wheat crops and responsible for up to 50% loss in yield. Azoles SDHIs are main groups fungicides used control disease. The efficacy these has decreased recent years due resistance development. Fungicide can be a result mutations target genes, upstream regulatory elements that over-expression proteins o...

Grove, Plant Pathology, WSU-IAREC, Prosser, WA Objectives • Develop a forecasting model to improve management of apple powdery mildew, caused by Podosphaera leucotricha. • Develop biorational disease and fungicide-resistance management programs • Lower disease pressure through cha...

Banana is the fourth most important staple food in the world, behind rice, wheat, and maize, with more than 100 million tons produced annually [1]. Although the majority of bananas produced are consumed locally, banana export is a multi-billion–dollar business [2]. Bananas are grown in more than 100 countries worldwide, largely in developing countries in tropical regions of Africa, Asia, and La...

Anthracnose, caused by Colletotrichum gloeosporioides (C. gloeosporioides; Teleomorph: Glomerella cingulata), is the most destructive disease that affects sweet persimmon production worldwide. However, the biology, ecology, and genetic variations of C. gloeosporioides remain largely unknown. Therefore, in this study, the development of fungicide resistance and genetic diversity among an anthrac...

Diseases of golf green turfgrasses cause unsightly spots and discolorations that are undesirable and unacceptable to golf course managers and the golfing public. The development of highly effective turfgrass fungicides has revolutionized disease management of turf, especially on golf courses. However, high levels of fungicides are required. Fungicide usage on golf courses, and greens especially...
