Josh is a long time user of the Central Life Sciences line of Grain Protection products on wheat and corn. He started using Centynal and Diacon IGR some years ago and moved up to Diacon Plus and PBO-8. Last year he switched to Gravista and really likes the fact that no mixing is required.
Josh just emptied his wheat bin after storing for 10 months and did not find the first weevil as they swept the floor clean. In addition to treating his wheat with Gravista as it goes into the bin, he fogs the inside of the bin with a combination of Pyronil Crop Spray and Diacon IGR. He also treats corn with Gravista and is very satisfied with the results he gets.
