Manganese sulfide nanospheres (MnS‐NSs) prepared in situ via sonochemical process were characterized to investigate the effect of nanoscale MnS on antifungal potential against mycopathogens of rice viz. Fusarium verticillioides, Drechslera oryzae and Curvularia lunata. MnS‐NSs dispersed in aqueous medium resulted in significant inhibition of growth of all the test fungi (ED₅₀ ≤ 18 μg/ml) at concentration much lower than standard commercial fungicides (captan and carbendazim with ED₅₀ ≥ 230 μg/ml) against respective fungi. The maximum per cent inhibition (98 ± 1.4) was recorded against C. lunata with a minimum ED₅₀ value of 14 μg/ml, followed by D. oryzae and F. verticillioides with ED₅₀ values of 17 and 18 μg/ml, respectively. Nanopriming of rice seeds with MnS‐NSs at 35 μg/ml for 8 hr resulted in significant reduction in seed rot (76%) and seedling blight (89.13%) along with enhancement in percent germination, root length, shoot length, dry weight and vigour index of seedlings by 33.7%, 55%, 66.3%, 85.3% and 89.3%, respectively, compared with control. Hydropriming of seeds was found to control the seed health parameters less effectively than nanopriming.

硫化锰纳米球作为杀真菌材料和真菌感染水稻种子的引发剂

硫化锰纳米球（MnS系NSS）原位制备经由声化学过程进行了表征研究纳米MnS的抗真菌潜在抗水稻的mycopathogens效果即。镰刀菌（Fusarium v​​erticillioides），米氏德拉毛（Drechslera oryzae）和弯弯曲菌（Curvularia lunata）。MnS系奈米球分散在水性介质中产生了所有的生长将实验真菌的显著抑制（ED ₅₀  ≤18微克/毫升）在浓度比标准市售杀真菌剂（克菌丹和多菌灵与ED低得多的₅₀  ≥230微克/毫升）与各自的菌类。以最小的ED ₅₀记录了对月球梭菌的最大抑制百分比（98±1.4）值分别为14μg/ ml，米曲霉（D. oryzae）和网状螺旋藻（F. verticillioides），ED ₅₀值分别为17和18μg/ ml。用MnS-NSs以35μg/ ml的浓度对水稻种子进行纳米引发8个小时，可显着减少种子腐烂（76％）和幼苗枯萎病（89.13％），并提高发芽率，根长，苗长，干重和与对照相比，幼苗的活力指数分别提高了33.7％，55％，66.3％，85.3％和89.3％。发现对种子进行水引发比纳米引发更不能有效地控制种子健康参数。
