Abstract: Penicillium dry rot of wheat (also known as Penicillium dry seed decay) occurs when wheat seed is planted into soils that are too dry to allow for timely germination of the seed. This is often done in semi-arid production regions with the expectation that precipitation will follow planting and stimulate seed germination. However, if precipitation does not occur in a timely manner the wheat seed may remain in dry soils for extended periods prior to germination and, as a result, Penicillium spp. can infect the seed and prevent it from germinating. The objectives of this study were to: i) determine the efficacy of experimental seed treatment EXP102 alone and in combinations with other Penicillium dry rot-effective products; and ii) evaluate each seed treatment product for negative effects on wheat germination and growth.
