Even though the seed tests indicate the seed lot is pathogen-free we still recommend a seed treatment with thizbendazole fungicide as added insurance. The rationale is simple. If only 1 in 400 seeds are infected, a 35 percent chance of not detecting the pathogen in the seed-testing program exists. Furthermore, if 1 in 400 seeds are infected, up to 50 infection loci will be present in each acre. Thiabendazole treatment, which is up to 95 percent effective, reduces the chances for the pathogen to establish from seed.
Seed only varieties that have some tolerance to the disease.
Sanford, Dwelly and B-90's have some early season tolerance but none are totally resistant. Do not select a field that is closer than 3 miles from a field grown to chickpea the previous year. We realize that this is a difficult recommendation, but it is important, especially if the disease was present in your production area the previous year. Be prepared to spray with a fungicide. Other Bravo formulations are not registered.
