Abstract: The present invention relates to the antagonistic bacteria for controlling the Fusarium wilt of continuous cropping banana and their microbial organic fertilizer. It belongs to technology of intensive agricultural production. The present invention separates two antagonistic bacteria NJN-6 and NJN-11 and produces the microbial organic fertilizer through inoculating the two said strains into pig manure compost and rapeseed cake compost to conduct solid-state fermentation. The microbial organic fertilizer is characterized in that in the fertilizer, the content of each of the antagonistic bacteria NJN-6 and NJN-11 is above 1×108 cfu/g, total nitrogen is 4˜5% (weight percent), above 90% (weight percent) of the total nitrogen is organic nitrogen, total nitrogen-phosphorus-kalium nutrient is 6˜10% (weight percent) and organic matter is 30˜35% (weight percent).

Abstract: The present invention relates to the antagonistic bacteria that are used to prevent and eliminate tobacco bacterial wilt and their microbial organic fertilizer, which belong to the technology for agricultural intensive production. The present invention separates two antagonistic bacteria (Brevibacillus brevis NJL-25 and Bacillus cereus NJL-14) that have remarkable antagonistic action against the pathogens of tobacco bacterial wilt. Microbial organic fertilizer is produced from these antagonistic bacteria and organic compost. Wherein, the content of each of NJL-25 and NJL-14 is above 1×1010 cfu/g, the content of total nitrogen is 4˜5% (above 90% of the nitrogen is organic nitrogen), the content of total nitrogen-phosphorus-kalium nutrient is 6˜10% and the content of organic matter is 30˜35%. As indicated by experiments, after the microbial organic fertilizer is applied into soil, it will enable rapid multiplication of the antagonistic bacteria into a dominant microflora in the soil and achieve more than 97.

Abstract: A method of eradicating weeds by applying to the weeds a compound derived from 3-acetyl-5-sec-butyl-4-hydroxy-3-pyrrolin-2-one.

Abstract: The present invention relates to a biocontrol strain against the wilt of continuous cropping cucumber and watermelon as well as its microbial organic fertilizer, which belongs to the technology for agricultural intensive production. The present invention separates Trichoderma harzianum SQR-T037, which has a remarkable biocontrol effect against wilt of cucumber and watermelon. Microbial organic fertilizer was produced from this biocontrol strain and organic compost. In this fertilizer, the content of the strain is above 1×108 cfu/g, the content of total nitrogen is 3˜5% (above 90% of the nitrogen is organic nitrogen), total nitrogen-phosphorus-kalium nutrient is 6˜10% and organic matter is 30˜35%. As indicated by the experiments, after this microbial organic fertilizer is applied to soil, it will enable rapid multiplication of biocontrol strain into a dominant microflora in the soil and achieve more than 85% of biocontrol rate of wilt in the soil suffering from serious cucumber and watermelon wilt.

Abstract: A composite biocontrol microbial agent PSX combination controls several soil-borne diseases. The PSX combination was composed of three biocontrol bacteria, which are shaking cultured in the PDA culture solution at 37° C., 180 rpm for 20 to 24 hours, then centrifugated at 4000 g for 10 min, taking the wet bacterium preserved fluid by the ratio of 1:40 to prepare the microbial agent, and then mixing at the ratio of 1:1:1, the total concentration of live bacteria in finished product being of 1×109˜1×1012 cfu/mL. The PSX combination controls soil-borne diseases of plant that occurs complexly or solely, including root knot nematode disease, bacterial wilt, verticillium wilt and blights. Its disease-preventing effect is 60-100%. Yield increase is 30-200%. The effects of preventing Fusarium wilt of banana and rice sheath blight disease are more than 50%, and have 20-80% yield increase. In addition, the PSX combination also can improve soil hardening.

Abstract: A series of herbicidal molecules derived from 3-acetyl-4-hydroxy-5-sec-butylpyrroline-2-ketone, a natural substance, and their potential use in agriculture for weed control. Through the modification of the 5-sec-butyl hydrocarbon chain and 3-acetyl group and the analysis of their biological functioning, newly designed molecules are superior to the original compound in herbicidal activity. These molecules inhibit the photosynthesis of the plants. The treated plants show significant damage in 24 hours and die within 3-5 days after the chemical treatment. In addition, the new molecule has relatively simple structure, they are easy to make and they have better physical properties. They are broad-spectrum, high potency herbicides.
