Damage and Control
When faba-bean rust is present, leaves of infected plants exhibit many small, orange-brown pustules, each surrounded by a pale yellow halo. Severely infected leaves wither and may drop from the plant. Larger pustules occur on the stems and isolated pustules may be found on the pods. Severe infection may result in reduced seed size and may cause yield losses of up to 30%, while in combination with chocolate spot, yield reductions of over 50% have occurred. Control measures include the use of resistant varieties of bean and the strategic use of foliar fungicides, which need to be applied before heavy infections occur to minimise crop losses.

Famous quotes containing the words damage and/or control:
“I came to explore the wreck.
The words are purposes.
The words are maps.
I came to see the damage that was done
and the treasures that prevail.”
—Adrienne Rich (b. 1929)
“There are many things children accept as “grown-up things” over when they have no control and for which they have no responsibility—for instance, weddings, having babies, buying houses, and driving cars. Parents who are separating really need to help their children put divorce on that grown-up list, so that children do not see themselves as the cause of their parents’ decision to live apart.”
—Fred Rogers (20th century)
