The precision of a modified tower for Uromyces phaseoli spore inoculation was assessed. Main parts of the tower are described and a picture included. In the 1st expt., the effect of the deposition control of U. phaseoli spores was studied on the uniformity of deposition during deposition times ra...

Yield losses due to Uromyces phaseoli were determined in 9 bean var. selected for pustule size: BAT 93, BAT 308, and EMP 81 (type 3 pustules; more than 300 millinicrons in diameter, approx.); Jamapa, ExRico 23, and BAT 883 (type 5 pustules; more than 500 millimicrons in diameter, surrounded by a ...

A total of 18 bean var. with different degrees of rust resistance in the field were subjected to 4 treatments, to obtain high severity of Uromyces phaseoli under low RH. Treatments were (1) greenhouse inoculation, with optimum temp. and RH for disease development, (2) field inoculation in infecti...
