*PAMPS is poly(2-acrylamido-2-methylpropane sulfonic acid) hydrogel (F8) and SA is salicylic acid, tobacco seed pelleting agents with different formulas; the control is the mixture of talc and bentonite without PAMPS hydrogel and SA; P1 and P2 are mixtures of PAMPS hydrogel, talc and bentonite without SA; S1 and S2 are mixtures of SA, talc, and bentonite without PAMPS hydrogel; P1S1, P1S2, P1S3, P2S1, P2S2, and P2S3 are mixtures of SA-loaded PAMPS hydrogel, talc, and bentonite. F8 (shown in Table 1) is the PAMPS hydrogel synthesized by 35 g of AMPS (2-acrylamido-2-methylpropane sulfonic acid), 0.021 g of KPS (Potassium persulfate), and 0.035 g of MBA (N, N′-methylene-bis (acrylamide)).
