Leaves of Perilla frutescens, commonly known as perilla are widely used in Korea, due to their medicinal properties. The rust disease of perilla interrupts its wide use every year. The present study was carried out to evaluate the control of perilla rust disease by using oak pyroligneous liquor having various biological properties. The rust disease infected perilla leaves were applied with 100 ...

Green rust (Fe(4)(II)Fe(2)(III)(OH)(12)SO(4).3H(2)O) is an intermediate phase in the formation of iron (oxyhydr)oxides such as goethite, lepidocrocite, and magnetite. It is widely considered that green rust occurs in many soil and sediment systems. Green rust has been shown to reduce sorbed Se(VI), Cr(VI), and U(VI). In addition, it is also reported that green rust does not reduce As(V) to As(I...

Oat (Avena sativa) is an important forage and grain crop in countries of the southern cone region of South America. Approximately 600,000 ha of oats are grown for grain in Argentina, Uruguay, and southern Brazil. Also, more than 4,000,000 ha are grown for forage (17,19,22), although in Brazil much of the forage oat is A. strigosa rather than A. sativa. In the subtropical to temperate climate of...

ABSTRACT Canadian wheat cvs. Pasqua and AC Taber were examined genetically to determine the number and identity of stem rust resistance genes in both. The two cultivars were crossed with stem rust susceptible line RL6071, and sets of random F(6) lines were developed from each cross. The F(6) lines, parents, and tester lines with single stem rust resistance genes were grown in a field rust nurse...

Leaf rust (caused by Puccinia recondita f. sp. tritici) is the most widespread and regularly occurring rust on wheat. Genetic resistance is the most economical method of reducing yield losses due to leaf rust. To date, 46 leaf rust resistance genes have been designated and mapped in wheat. Resistance gene expression is dependent on the genetics of host-parasite interaction, temperature conditio...

ABSTRACT: In recent years, there have been reductions in the efficacy of fungicidal control Phakopsora pachyrhizi, thereby hindering management soybean rust and compromising crop yield. This study evaluated effects incorporating hydrogen peroxide (H2O2) commercial fungicide formulations on rust. We conducted two experiments, one which was performed a greenhouse environment other under field con...
