" Print the page Marketing and use of mould-affected grain often presents a dilemma for growers and livestock producers, and usually comes down to how much the grain should be discounted... The first group is ergot alkaloids, produced by sorghum ergot growing prior to harvest, and the second is aflatoxins, which are mainly produced if sorghum is stored with high moisture content... The results in: shrunken and pinched grain, following drought or from soil fertility constraints discoloured grain, often covered with black, gray, pink or orange fungal growth (mould), after extensive warm, humid periods during grain maturation premature germination of the grain caused by wet or humid weather conditions at harvest, resulting in sprung, shot or sprouted grain...

Affected pods go grey inside in the early stages, then the whole pod rots (left); note the characteristic small black resting bodies on the stem (right) Collar rot or lasiodiplodia: bushes rapidly wilt and rot at ground level.. The disease seems to be worse where the soil is degraded through erosion or scalping during land levelling... Infection occurs at soil level where stems and crowns suffer from heat stress, soil abrasion or drought...
