A process for applying a pesticidal composition to granular vegetative products such as grains and seeds, which comprises: 1. loading and compacting a granular material into a first chamber by conveying it upwardly against the force of gravity; 2. conveying and tumbling the compacted granular material from the first chamber into a second chamber of greater capacity than the first chamber to permit mixing and tumbling of the granular material; 3. spraying the tumbling granular material with a pesticidal composition in the second chamber; and 4. discharging the sprayed granular material from the second chamber. Apparatus suitable for carrying out the process of the invention are also described.
