The results showed that germination potential and rate both improved around 5% and the num- ber of root increased by 4% in the treatments with ultra-fine powder shaped maize seed coating agent compared with the control group without seed coating. What＇s more, the treatments with ultra-fine powder shaped maize seed coating agent took advantages in terms of fresh weight of seeding, stem diameter, and dry weight. It is notable that control effects on underground insects performed the best, with per- centage over 94%, which is more excellent relative to other agents in markets. Therefore, ultra-fine powder shaped maize seed coating agent can be widely applied in spring sowing areas in northeast China, without side effects.展开更多

Similarly during the study of antimicrobial susceptibility pattern in the microflora, a multidrug resistant bacterium has been isolated from soil collected in Maharashtra state （India）. The bacterium exhibited a resistance to various classes of antibiotics namely glycopeptide, beta-lactams, aminoglycosides, macrolides and lincosomides. The bacterial strain showed its resemblance to the genus Paenibacillus. This constitutes the first report of its kind as to the multi-drug resistance trait in the genus Paenibacillus phenotype, especially in close phylogenetic neighbour of Paenibacillus daejeonensis. The resistance pattern displayed by this strain particularly highlights the possible presence of multiple resistant determinants in microflora of the soil rhizosphere. In view of the recent reports about the Paenibacillus spp. in clinical derived strains, such multi-drug resistance factors in this genus adds to menace of transmission of resistance to common soil originating pathogen. The data also supports the fact that the resistances to certain antibiotics need not always be due to exposure to particular antibiotic or similar substance.展开更多
