Summary
In six field trials, sixteen chemicals were compared against common scab, with quintozene as standard, by application to soil before planting. Captafol was as effective as quintozene, and did not decrease yield, but the closely related chemicals captan and folpet were ineffective. The other chemicals, of which over half were dihydroxybenzenes or dithiocarbamates, also failed to decrease scab. or decreased yield, or both.
