Control of stem-gall of coriander by fungicides

Summary The stem-gall caused byProtomyces macrosporus Ung. is a common disease of coriander which is an important spice crop of India and other countries. For the first time, it has been possible to obtain at least a partial field control of this disease, through seed treatment with thiram at the dose of 0.25 kg per 100 kg of seed. There are indications that better control is possible by combining seed and soil treatments with thiram. Seed treatment with TCNA — an experimental fungicide — may prove to be effective at a dose of 0.5 kg per 100 kg of seed.The authors are grateful to Dr.N. K. A.
