Jinggangmycin Nanocapsules Preparation and the Inhibitory Control of Rice Sheath Blight
Jinggangmycin nanocapsules with Jinggangmycin as the core material were prepared by microemulsion polymerization.Transmission electron microscopy(TEM)showed that all the sizes of nanocapsules were around 100 nm and uniform distribution.Against rice sheath blight indoor toxicity test results showed that the half effect concentration values(EC50) of Jinggangmycin nanocapsules was 4.23 μg/mL,with an efficacy 88-fold over the original drug.Field experiments showed that the treatment effect of Jinggangmycin nanocapsule was 1.2 times the original for the same 5 μg/mL concentration.
