Strawberry anthracnose, caused by Colletotrichum acutatum J. H. Simmonds, is one of the most serious diseases in commercial strawberry production. Even in well-managed fields, losses due to the fruit-rotting phase can exceed 50% when conditions favor disease development (10). Historically, the disease has been thought of as a “southern” disease (16), occurring primarily in the warmer production...

Although citrus is indigenous to southeast Asia, oranges were first planted commercially in central Arizona in the late 1800s. Today commercial production is centered in several warm and low-frost-risk areas of central and southwestern Arizona. A great number of citrus varieties are also widely planted in home gardens. Many diseases of citrus have been described world wide and have colorful and...

The fruits showing brown rot symptom on dwarf flowering almond were found in Gongju, Chungchungnam-Do in Korea in July 2005. Small water-soaked lesions on the fruits were initiated, and gradually developed to soft rot covered with gray conidia. Then the diseased fruits were shrunk and became grayish-black mummies. A fungus was isolated from the diseased fruit and its morphological, cultural and...

Anthracnose basal rot (Colletotrichum cereale) is a common and difficult to control disease of annual bluegrass (Poa annua) putting greens. While various cultural practices and fertility programs have been developed to reduce disease symptoms, fungicides are generally required to provide additional suppression. Due to the fact that anthracnose is generally more severe on under fertilized turfgr...

Biological control of fungal plant pathogens can improve global food availability, one of the three pillars of food security, by reducing crop losses, particularly for low-income farmers. However, the interrelationships of many environmental variables can result in multiple interactions among the organisms and their environment, several of which might contribute to effective biological control....

The effects of silicon (Si) amendment have been studied in several plant/pathogen interactions; however, studies in horticultural tree crops are limited. Effects of amendment with soluble potassium silicate (AgSil®32, approximately 30% available Si), or milled cement building board by-products (Mineral Mulch (MM) or Mineral Dust (MD), containing 5% available Si) were investigated in field and g...
