T under intensive management are often subject to outbreaks of infectious diseases. Diseases usually are most damaging when weather or cultural conditions favor the disease-causing agent but not plant growth and vigor. Cultural conditions that enhance turfgrass diseases include close mowing, inadequate or excessive nitrogen fertility, light and frequent irrigations, excessive thatch, poor drain...
A sensitive gas chromatographic method using an electron-capture detector (ECD) has been developed for the determination of tetraconazole and diniconazole fungicide residues in tomatoes and green beans. The developed method consists of extraction with methanol, partition with methylene chloride, and column chromatographic clean-up, followed by capillary gas chromatographic determination. The re...
Two field experiments were conducted at domar and sadar upzilla of Nilphamari district to find out an effective control measure against rhizome rot (Pythium aphanidermatam) disease of ginger (Zingiber officinale Rose). Each experiment consisted of nine treatments, where three fungicides (Ridomil, Metataf and Secure), three organic amendments (poultry refuse, mustard oilcake and saw dust burning...
Chemical fungicides are used worldwide for enhance crop yield and control plant diseases. When crops are treated with chemical fungicides over a long period then some fungi develop resistance to these chemicals beside this these chemicals are harmful to other non target microorganism and disturb microbial community of soil. In view of these facts, it is urgent need to discover eco friendly, ren...
Recent research of the Agricultural Research Service of USDA on the use of natural products to manage pests is summarized. Studies of the use of both phytochemicals and diatomaceous earth to manage insect pests are discussed. Chemically characterized compounds, such as a saponin from pepper (Capsicum frutescens L), benzaldehyde, chitosan and 2-deoxy-D-glucose are being studied as natural fungic...
Biological characterization of fenpicoxamid, a new fungicide with utility in cereals and other crops
BACKGROUND The development of novel highly efficacious fungicides that lack cross-resistance is extremely desirable. Fenpicoxamid (Inatreq™ active) possesses these characteristics and is a member of a novel picolinamide class of fungicides derived from the antifungal natural product UK-2A. RESULTS Fenpicoxamid strongly inhibited in vitro growth of several ascomycete fungi, including Zymosepto...
Retinal degeneration is the leading cause of visual impairment in older adults. An association between retinal degeneration and fungicide use was observed previously among farmer pesticide applicators in the Agricultural Health Study, a large study of farm families from Iowa and North Carolina. The objective of this investigation was to determine whether wives of these farmer pesticide applicat...
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...

Fungicides are moderately hydrophobic and have been detected in water and sediment, particularly in agricultural watersheds, but typically are not included in routine water quality monitoring efforts. This is despite their widespread use and frequent application to combat fungal pathogens. Whereas the efficacy of these compounds on fungal pathogens is well documented, little is known about thei...
