Provided herein are exemplary methods for increasing crop yield. One exemplary method for increasing a yield of a crop includes controlling plant tissue stress by at least partially coating a plant tissue with a composition comprising an agricultural sunscreen formulation and a second agricultural chemical. The agricultural sunscreen formulation and the second agricultural chemical may be applied to the plant tissue from separate containers, wherein each container either contains the agricultural sunscreen formulation or the second agricultural chemical. Further, the agricultural sunscreen formulation and the second agricultural chemical may be applied to the crop at or near the same time. Alternatively, the agricultural sunscreen formulation and the second agricultural chemical may be applied to the crop from a shared container, wherein the shared container contains both the agricultural sunscreen formulation and the second agricultural chemical.
