chickpea blight caused by didymella rabiei is considered as the most important disease of chickpea in kermanshah province. the disease is seed borne in addition to being persistent on infected residues, secondary infection taking place through pycnidiospores. in laboratory tests, the effects of six fungicides were tested at : 0.01, 0.1, 1.0, 10.0 and 100.0 ?g.a.i.ml-1 csma(chickpea seed meal ag...

The systemic fungicide carboxin (5,6-dihydro-2-methyl-1,4-oxathiin-3-carboxanilide) inhibited oxidation of succinate by membranes prepared from Micrococcus denitrificans, the K(i) being 16 muM. Oxycarboxin (5,6-dihydro-2-methyl-1,4-oxathiin-3-carboxanilide-4,4-dioxide), F831 (5,6-dihydro-2-methyl-1,4-oxathiin-3-carboxanilide-4-oxide), and another succinate oxidase inhibitor, 4,4,4-trifluoro-1-(...

Field experiments were conducted for control of the southern root-knot nematode (Meloidogyne incognita) and cotton seedling disease fungi (primarily Thielaviopsis basicola) in one naturally infested field during 1999 and 2000 and in three additional fields in 2000. Treatments included: seed-applied fungicides (triadimenol + mefenoxam + thiram and carboxin + PCNB + mefenoxam), cultivars (Paymast...

Three new structures of Escherichia coli succinate-quinone oxidoreductase (SQR) have been solved. One with the specific quinone-binding site (Q-site) inhibitor carboxin present has been solved at 2.4 A resolution and reveals how carboxin inhibits the Q-site. The other new structures are with the Q-site inhibitor pentachlorophenol and with an empty Q-site. These structures reveal important detai...

Root rot disease caused by the fungus Phytophthora capsici can cause up to 60% yield loss of pepper in West Kalimantan, which is spread across Singkawang, Bengkayang, Pontianak, Sintang, and Sekadau Regencies. Control BPB chemically with fungicide considered be effective enough suppress both vitro field. This study aims examine effectiveness several active ingredients that are widely used contr...
