| The incidence of bean rust (Uromyces appendiculatus) was monitored in monthly plantings from March to December 1986 using the highly susceptible variety, Long Tom. The disease was found to be more severe during the winter months with a peak of 25 per cent in July. It was practically absent in summer. Seven fungicides were evaluated at two dosages for the control of the disease. Infection was reduced by all treatments. However, none of them significantly increased yield, except bitertanol (Baycor 300 EC) at 400 and 800 ml/ha. The results also indicated that foliar infection exceeding 5 percednt has a deleterious effect on yield. In field trials to evaluate reaction to rust, 32 entries were rated resistant, 14 susceptible and 21 highly susceptible. Integrated control of the disease using chemical treatment, resistant cultivars and cultural practices is discussed. | |
