India on improving soil conditions, controlling plant diseases & increasing plant yields and quality. Sweden Eritrea A plot consisted of two rows, 60 cm wide and 5 m long. Poland Spain Due to this property, this bacterium is used in many insecticides and pesticides. Plots were treated by the bio-control agents, i.e., bio-arc (a commercial product of Bacillus megaterium (20 ml/plant)); nemastrol (a mixture of active ingredients at 0.25 ml/plant) was applied two times at 1-week interval; humisun (a commercial product of humic acid) was applied at the rate of 100 ml/plant and powdered dried sweet basil callus (O. basilicum) as well as native leaves were applied three times at 1-week interval at the rate of 0.1 g/plant and incorporated into soil. Guernsey Botswana Technological characters in terms of sucrose (17.1%), TSS (21.8%), and purity (79.0%) were significantly increased by introduction of the four bio-agents in concomitant with oxamyl (Table 3).

Similar trend was also noticed with root diameter and number of leaves of sugar-beet infected with Meloidogyne spp. Argentina revealed that integrated of two or more components gave better results in sugar beet growth parameters than did single ones (Table 1).

Bahrain Also humic acid treatments improved the yield of grape infected with M. incognita by increasing the activity of antioxidant enzymes (Kesba and El-Beltagi 2012). Additionally, the greatest suppression in nematodes’ population (95.7%), root galling (83.0%), and number of egg masses (100%) was also sustained at the soil amended with nemastrol + humisun + bio-arc + sweet basil callus + oxamyl since incorporation of such organic materials into soil might enhance B. megaterium activity that initiates antibiotics towards nematode population. (2014) and El Deriny (2016) in respect of microbial activity, i.e., B. megaterium in the soil is enhanced on incorporation of organic matter that initiated antibiosis towards the nematode activity. Bacillus megaterium, which is a Gram-positive bacterium, belongs to the genus Bacillus. Namibia Gibraltar Root galling (83.0%) and egg masses number (100.0%) were significantly suppressed for such treatment.
