What is the safe disease rating on seed for planting?
There are no official “safe” infection levels for planting. The more disease-free the seed, the better it is for seeding. The decision to use infected seed lies entirely with the farmer – after considering such factors as: cost and availability of disease-free seed; cost and availability of registered seed treatments; weather conditions and disease pressure; type of pulse crop; type of disease; and cost and availability of foliar fungicides. Below are unofficial guidelines that may be used when planting seed with seed-borne pathogens.
