Banana Crown Rot Postharvest Disease Banana is one of the most important tropical crops and is affected by several fungal diseases, such as crown rot postharvest disease [1]. Crown rot is responsible for significant losses in banana fruits [1, 2]. Predominantly, Colletotrichum musae and Fusarium spp. are its causative agents [1, 2]. Inoculum sources include mainly infected flowers but also deca...

Phytophtora crown- and root- rot is one of the important soil-borne diseases of strawberry grown in hydroponic culture. Plant roots affected by root and crown rot show yellowish and decline symptoms and the plant perishes and dies gradually. To identify the factor responsible for strawberry crown rot, some samples were taken from infected plants. The samples were washed with tap water for 1-2 h...
Two methods to induce a symptomless infection of crown rot (Phytophthora cactorum) in stolons of three strawberry (Fragaria×ananassa) cultivars were evaluated. Spraying a 10−4 ml zoospore suspension was the most effective method, producing a mean infection rate of 12%. Meristem cultures were subsequently established from all of the inoculated stolons and tested eight weeks later for the presenc...
BACKGROUND Soybean red crown rot is a major soil-borne disease all over the world, which severely affects soybean production. Efficient and sustainable methods are strongly desired to control the soil-borne diseases. PRINCIPAL FINDINGS We firstly investigated the disease incidence and index of soybean red crown rot under different phosphorus (P) additions in field and found that the natural i...
Crown rot is one of the main important fungal diseases affecting wheat in many areas of the world, including Australia, USA, and Iran. Until now, there had been no report of this pathogen in Iraq. Plants displaying crown rot symptoms were observed in Shaat Alarab (Basra, Iraq); we investigated the causal agent of the disease. Samples were surface-sterilized in bleach (1% available chlorine...
Crown rot caused by fungal pathogen is the most prevalent postharvest disease in banana fruit that results significant economic losses during transportation, storage, and ripening period. Antifungal effects of ultraviolet C (UVC) irradiation at doses varied from 0.01 to 0.30 kJ m-2 were investigated in controlling postharvest crown rot disease, maintenance of fruit quality, and the effects on a...
Scott, J. B., Gent, D. H., Pethybridge, S. J., Groom, T., and Hay, F. S. 2014. Crop damage from Sclerotinia crown rot and risk factors in pyrethrum. Plant Dis. 98:103-111. Sclerotinia crown rot, caused by Sclerotinia sclerotiorum and S. minor, is a prevalent disease in pyrethrum fields in Australia. Management involves fungicide applications during the rosette stage of plant development from au...
Different species of Phytophthora cause serious and economically important soilborne diseases of citrus throughout the World. Tree and crop production losses occur from damping-off of seedlings in the seedbed, root and crown rot in nurseries, foot rot and fibrous root rot, and brown rot of fruit in groves. Foot rot results from infection of the bark near the ground level producing lesions on th...
