As toxic pesticide residues may persist in agricultural soils and cause environmental pollution, research on natural fungicides to replace the synthetic compounds is currently increasing. The effect of the synthetic fungicide chlorothalonil and a natural potential fungicide on the soil microbial activity was evaluated here by the substrate-induced respiration by addition of glucose (SIR), as bi...

Alternaria solani Sorauer (Ellis), a foliar pathogen of potato (Solanum tuberosum L.), was considered to be difficult to control, responsible for yield losses of up to 30% (24), until the registration of the first strobilurin fungicide, azoxystrobin (Quadris; Syngenta Crop Protection, Greensboro, NC), in 1999. Strobilurins belong to the group of chemicals classified as Quinone outside inhibitor...

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 ...

In a series of screening trials a number of new, non-mercurial fungicides have shown promising results in controlling pineapple disease of sugarcane (Ceratocystis paradoxa). Several of the fungicides tested are as effective as Aretan and Benlate and are now registered for use in sugarcane. Growers now have a choice of effective non-mercurial fungicides for sett dip treatment. Poor germination o...

The use of fungicides in crop protection still effectively eliminates fungal pathogens of plants. However, fungicides may dissipate to various elements of the environment and cause irreversible changes. Considering this problem, the aim of the presented study was to evaluate changes in soil biological activity in response to contamination with azoxystrobin. The study was carried out in the labo...

Abstract Fungicide protection is the current approach for management of boxwood blight caused by Calonectria pseudonaviculata ( Cps ) and C. henricotiae Che ). However, published studies evaluating fungicides under field conditions have been focused on . The objective this study was to evaluate in Northern Germany where both were present. Three trials conducted between 2006 2016. In 2006, plant...

Tempranillo grapes were immersed in solutions of pyrimethanil, metalaxyl, dichlofluanid and penconazol fungicides at different concentrations for several different times. Determinations of the fungicide residues was carried out by GC-NPD, with an additional confirmation by GC-MS. The percentage absorption was determined as well as the distribution between surface, skin and pulp of the grapes. T...

Fungicide action is generally assumed to be dependent on an antibiotic effect on a target pathogen, although a role for plant defense mechanisms as mediators of fungicide action has not been excluded. Here, we demonstrate that in Arabidopsis, the innate plant defense mechanism contributes to the effectiveness of fungicides. In NahG and nim1 (for noninducible immunity) Arabidopsis plants, which ...

Andersen, K. F., Morris, L., Derksen, R. C., Madden, L. V., and Paul, P. A. 2014. Rainfastness of prothioconazole + tebuconazole for Fusarium head blight and deoxynivalenol management in soft red winter wheat. Plant Dis. 98:1398-1406. Fungicides are most warranted for control of Fusarium head blight (FHB), a disease of wheat caused by the fungal pathogen Fusarium graminearum, when wet, rainy co...
