The Antagonism of an isolate of Trichoderma sp. from soil by our lab, T 1, against Rhizoctonia solani was tested in vitro by dual culture. The mechanisms of antagonism of Trichoderma sp. including competition, mycoparasitism, antibody-secretion and cell lysis were investigated primarily. The application of Trichoderma sp. in biological control of cucumber Rhizoctonia solani was carried out in flower vessel, and the results showed that the effect of Trichoderma sp in bio-control against cucumber Rhizoctonia solani reached 93%, and this effect can be retain long time and promote the growth of crop.

Trichoderma species are one of the most common soil fungi, isolated from various habitats, Most of the Trichoderma strains are mesophilic and grow well in a wide range of temperature from 15-35 °C. Low temperatures in winter may cause a problem during biological control by influencing the activity of the Trichoderma. Trichoderma species are best friends of higher plants. They not only protect them by killing or antagonizing their enemies but also improve their overall health including toning up of their ability to tolerate diseases and pests. They act as symbiont and may colonize epidermal and cortical cells.

Some Trichoderma strains are promising biocontrol agents (BCAs) of plant disease. It is observed that chitinolytic enzymes of Trichoderma play an important role in mycoparasitism which is considered as one of the mechanisms involved in the antagonism of Trichoderma against plant fungal pathogens. The induced production, the physical and chemical characteristics of chitinases from Trichoderma strains and their antagonism against plant fungal pathogens are reviewed in the present article, and the potential use of the chitinases and chitinase genes from Trichoderma for biological control is also discussed.

【Objective】A study on the biocontrol efficacy of the Bacillus strains A57,A178 and N1729 against 13 Botrytis cinerea isolates from the different area in Xinjiang,was performed for evaluating the future application significance of the three strains for the biological control of plant diseases,and providing scientific basis for the future research on their development.【Method】The antagonism of three biocontrol bacteria were tested on PDA plate against 13 Botrytis cinerea isolates respectively.By the liquid fermenting and the tiny hole filters,the antagonism of free cell filtrates were detected on PDA plate.【Result】The results demonstrated,the antagonistic ability of A178 strain was the strongest among three biocontrol bacteria,the average inhibition rate of the strain was 45.67%.The average inhibition rate of N1729 strain' free cell filtrates was 44.61%.A57 strain had the better antagonistic ability to the pathogen,but its free cell filtrates had no effect on the pathogen.【Conclusion】These evidences showed that the two strains A178,N1729 were excellent biocontrol material against Botrytis cinerea with good prospects of development and application.

The use of biological agents is becoming an increasingly important alternative to chemical control against insects, weeds and diseases in agriculture. The success of this method depends on the nature antagonistic characters and the mechanisms of action of microorganism. Fungi are the most important biological agents against plant pathogens. Trichoderma species are common filamentous imperfect fungi. The mycoparasite ability of Trichoderma species against some economically important plant pathogens allows for the development of biocontrol strategies. In this research, the effect of biocontrol of Trichoderma species on some plant pathogens was investigated. The results showed a direct inhibition of the pathogenic microorganisms by Trichoderma species. Hence Trichoderma species can be considered as biocontrol agents for control of some plant pathogens.

The fungous Trichoderma is an important microorganism in the biological control of plant diseases.The antagonism of Trichoderma harzianum NF9 and Trichoderma virens TY against three soil-borne plant fungous pathogens,Fusarium oxysporum Schl.f.sp.cucumerin Owen,Sclerotium rolfsii and Fusarium oxysporum Schl.f.sp.niveum,were tested in vitro by dual-culture.The result showed that two Trichoderma isolates had antagonism effect on the tested pathogens,and Trichoderma harzianum NF9 was better than Trichoderma virens TY in antagonism effect.

The beneficial interaction on controlling grey mold caused by Botrytis cinerea was shown by a combination of Trichoderma spp. and lower concentration of procymidome. In the interaction test, the efficiency was 85.0%, by application of Trichoderma spp. and procymidome at 10∶80, higher than the treatment of antagonistic Trichoderma or procymidone only. And application of antagonism and chemical, chemical, antagonism,respectively, to control cucumber grey mold caused by Botrytis cinerea with 1 000 times liquor, the efficiency was 67.6%,62.5% and 51.5% and compared with treatment of Trichoderma only, these treatments reduced the ability of infection of pathogens and the dosage of chemical.
