Plowing cotton stalks under is an effective method of destroying the food supply of mature weevils and ending the lives of immature weevils where there are few stumps and roots, where the cotton stalks are small, and where large plows and strong teams can be had. Farmers who have attempted to plow under green cotton stalks early in the fall, laugh at the advice sometimes given to plow under the stalks at all times and under all conditions as a means of destroying the food supply of the weevil. They know from experience that such advice is often better theory than practice as the plowing under of green cotton stalks is very often a decidedly obstinate proposition. However, where large plows and strong teams are available, use them and completely bury the cotton stalks wherever it can be done. [Illustration: Velvet beans yield abundant crops and add nitrogen to the soil. A good crop for weevil territory] Burning the stalks is a practical method of destroying the weevils. On many farms and plantations there are not cattle enough to strip the cotton stalks thoroughly and completely of every particle of foliage, squares and bolls in a short time by pasturing. It is also often impossible to completely bury the cotton stalks. In such cases, it is absolutely necessary to cut, dry and burn them as soon as the cotton can be picked. By burning the stalks, the food supply of the adult weevil is destroyed, and weevils in immature stages in the squares and bolls are destroyed. A large majority of the adult weevils also perish in the flames, especially when the stalks are burned after sundown, as weevils retire to the stalk piles for the night at about that time. They seldom move about at night, and if care is taken not to disturb them when applying the torch, practically all will be destroyed. Of course, if the stalks are allowed to remain until a heavy frost has come, practically all of the mature weevils will have gone into winter hibernating quarters and the immature weevils in the squares and small bolls will have been frozen. Nothing will be gained in that case by burning the stalks and the best thing that can be done will be to cut the stalks and turn them under as deeply as possible. =Clean Up Hibernating Quarters:= Many weevils escape from the fields but all do not fly beyond the reach of the farmer. Surprising numbers have been found hibernating in cracks and holes in the ground and under grass, weeds and other trash. In January, 1907, in one instance, the United States Bureau of Entomology found 5,870 weevils per acre of which 70 per cent were alive. Most of the many examinations that have been made have shown more than one thousand live weevils per acre in the cotton fields. Many are found along the fence rows, hedges, ditch banks and in decayed logs and dead trees. Thousands more are found hibernating in nearby cornfields and old sorghum, cane and hay fields.
