Key Techniques for Integrated Management of Pepper Blight

This paper summarized the results of the studies on the management tactics of pepper blight in Gansu province.It demonstrated the relationship between occurrence epidemic of this disease and mating types,microbes level in soil,temperature and humidity,cultivating conditions,management level.Taking the combination of agricultural and agrochemical measures can control effectively damage caused by this disease.The integrated management strategy with agricultural control as the base and the chemical control as the key link was worked out and played a important role on the controlling this disease in Gansu and its neighborhoods.
