Bacterial blight of chickpea (Cicer arietinum) is caused by bacterium Xanthomonas campestris. They ejected tissue collapse and are digested by bacteria. The rapid spread of bacterial infection occurs through vascular strand. The stems and leaves of infected plant give blighted or burnt up appearance. Control measures include rogueing; 3- year crop rotation, disease free seeds, a spray of copper fungicides and antibiotics besides showing disease resistant varieties.
Bordeaux mixture is a most common fungicide, it was first discovered by Millardet in 1882 at the university of Bordeaux France to control downy mildew of grapes. It is prepared by mixing copper sulphate, lime and water in the ration of 4: 4: 50.
