To "sweat out the toxins", the farmers must stop using them. If we keep dumping pesticides into the environment, the toxins will keep accumulating. Crop rotation is good, but the crops are still susceptible to pests. So if they do use crop rotation and such, will they not spray pesticides?
Pesticides kill pests, but plants that are naturally resistant to pests don't necessarily kill pests. They have something in them that repels pests.
Pests normally destroy crops, so if cotton is infected, I don't think it'll survive.
In Canada, they grow genetically modified potatoes and tomatoes (and other stuff). These crops are resistant to certain pests that they'd otherwise be susceptible to...this gives the farmers a larger yield. Plus the farmers don't have to spray pesticides to ward off those pests.
'My' idea may be too far in the future to be of any help to Punjab.
The thing is that Punjab needs to take some sort of step (very soon) to reduce the toxins.
