Haptens, bioconjugates, and antibodies for highly sensitive immunochemical analysis of the new-generation fungicide penthiopyrad are described. Two haptens with equivalent carboxylated linkers were prepared, and the purified active esters were efficiently coupled to proteins. The results revealed slightly different antibody-eliciting capacities for the two synthetic derivatives. All of the prod...

The soil-borne fungus Rhizoctonia solani causes damping-off on sugar beet seedlings. Growers rely fungicides to protect in fields affected by R. solani. Quinone outside inhibitor (QoI) fungicides, such as azoxystrobin, have been applied in-furrow and foliar sprays manage solani, but repeated use of QoI pose risks fungicide resistance. Penthiopyrad is a novel with the succinate dehydrogenase (SD...

Zymoseptoria tritici is the causal agent of Septoria blotch (STB), a disease wheat (Triticum aestivum) that results in significant yield loss worldwide. Z. tritici’s life cycle, reproductive system, effective population size, and gene flow put it at high likelihood developing fungicide resistance. Succinate dehydrogenase inhibitor (SDHI) fungicides (FRAC code 7) were not widely used to control ...

This study investigated the sensitivity of 92 isolates Passalora fulva from tomato plants in Wakayama Prefecture to thiophanate-methyl, penthiopyrad, boscalid, azoxystrobin, and triflumizole using agar dilution methods. All exhibited reduced more than two fungicides. Bioassays seedlings showed that mancozeb WP (wettable powder), TPN WP, iminoctadin-albesilate were effective against strains resi...

rhizoctonia solani is the most serious problem on sugar beet beta vulgaris l. grown in north dakota and minnesota. picoxystrobin, a quinone outside inhibitor, and penthiopyrad, a succinate dehydrogenase inhibitor, were used alone and in combinations for controlling r. solani ag 2-2 iiib on sugar beet under greenhouse conditions of 22 ± 2 °c and a 12-h photoperiod. fungicides were applied in-fur...
