Dealing with herbicide and pesticides poisoning

Dear Daktari, Thank you for your weekly advice on how we can improve farming. I am a farmer in Kitale, and I insist my farmhands buy the Saturday Standard to read the Smart Harvest and specifically your articles on livestock because there is always something to learn in there. I recently watched the news about a farmer who lost his entire herd after spraying his cattle with pesticides meant for tomatoes. I have also in the past read about another farmer who lost his herd after they broke into and grazed on wheat that had just been sprayed with herbicides.
