Check your bins

[mcfarms]

Have found malathion dust to be far more effective than protect-it. Treat every load of cereals going into bins of all sizes with heavier concentration at peak of bin and have virtually eliminated any rusty grain or wheat aphid issues. Well worth the expense for the peace of mind it bring

Hope you don't put canola in those bins.

Have filled aforementioned bins with lentils, peas, and chickpeas on several occasions after thorough cleaning following cereals and have never had any issues. Designate canola to bins that are specific to our canola production only Use a 40 lb bag of malathion dust for every 2 superb-train loads of cereals going into bins. I acknowledge your concern with residual contamination but it hasn’t been a problem with a little careful management.
