Reducing copper and chlorothalonil in staked tomato production on Virginia's Eastern Shore
… annual gross value is $30,800,000. Copper and chlorothalonil have long been considered essential to control bacterial and fungal diseases in fresh market tomatoes. High rates of these fungicides on tomatoes grown under plastic mulch have led to concerns about their potential adverse effect on …

Study on the properties of gold nanoparticles as plasmonic sensing material for chlorothalonil detection
Chlorothalonil-based fungicide has been employed extensively to prevent various fungal diseases in plants to increase yield of crops. Conversely, over-usage of chlorothalonil can have adverse effects to human health and environment. An optical sensor implemented Localized Surface Plasmon Resonance …

Improved Strategies for Dollar Spot Suppression Using Ferrous Sulfate
… may supplement traditional fungicide use. Chlorothalonil is the most common fungicide used to suppress dollar spot in turfgrass. Annual site-use limitations of chlorothalonil often prevent turf managers from achieving acceptable dollar spot control throughout the season. It is not known how …

Development and evaluation of a computerized leafspot advisory program for effective use of cultivar resistance, fungicide, and spray adjuvant to control early leafspot of peanut
… trials used Florigiant peanut and the fungicide chlorothalonil (1.26 kg/ha). The 89-ADV program with TDVi=48 performed exceptionally well for three consecutive years in field tests and in simulated disease environments reconstructed from historical weather data. Benefits of this program compared …

Evaluation of fungicide resistance in Sclerotinia minor and strategies for chemical control of sclerotinia blight of peanut
… of peanut with iprodione in Virginia. The use of chlorothalonil for leafspot control has been correlated with an increase in the incidence of Sclerotinia blight. Excised peanut stems obtained from plots exposed to field applications of chlorothalonil produced larger lesions after inoculation with …

Seawater survival and osmoregulation of Atlantic salmon (Salmo salar) parr-smolts exposed to four different pesticides
… to sublethal concentrations of cypermethrin, chlorothalonil, quintozene or atrazine to determine if they affected osmoregulation. After 96 h of exposure to a pesticide, Na+K+-ATPase, hematocrit, liver somatic index (LSI), plasma sodium, chloride, and cortisol concentrations were determined. …

Investigating the interactive effects of ultraviolet-B radiation and pesticides in amphibians
… (1) α-cypermethrin (pyrethroid insecticide) and chlorothalonil (organochlorine fungicide) are most toxic to X. laevis embryos and larvae; (2) X. laevis larvae can be used as a surrogate species for endemic amphibians in risk assessments of pesticides; (3) α-cypermethrin and UVB had synergistic …

Competitive Effects of Perennial Ryegrass and Chewings Fescue on Bermudagrass Seed Establishment
… fungicide applications of propiconazole and chlorothalonil maintained high density and turf quality which inhibited successful establishment of bermudagrass during either year. Bermudagrass establishment in 1996 was moderately successful in plots not treated with fungicides; however, due to …

Natural and Anthropogenic Drivers of Variation in Bumble Bee Gut Microbiotas
… 3. There, I found that exposure to the fungicide chlorothalonil for a short, field-realistic duration did not alter bumble bee fecal microbiota community structure regardless of concentration, and that fecal microbiota structure did not accurately reflect gut microbiota structure. In Chapter 4, I …
