John, a farmer, is facing the problem of cotton-root diseases in his field. Which type of forage should John use to control cotton-root diseases in his field?

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.

Yes yes yes very good
