The Division concern itself with establishing feasible guidelines for pesticides applications. To achieve this goal, the toxicity and efficacy test of pesticides for major pests, improvement of pest control techniques development of integrated crop management programs were the major research topics to provide farmers with safe, economic and effective means of using plant protection tactics. In recent years, the Division has successfully developed IPM programs for grape and mango orchards, respectively. Baseline toxicity data were established for Phytophthora, Colletotrichum, Botrytis, Plasmopara, as well as many post-harvest diseases. The Division also completed an IPM program for major insect pests on the cruciferous crops and a simple and effective sampling plan for thrips on eggplants. In addition, monitoring and forecasting techniques were established for the Oriental fruit fly and important plant diseases. The Division plans to focus on establishing basic toxicity and efficacy data in using pesticides on major pests, improving ICM programs for major crop-systems, and actively engaging in the nationwide Plant Health Information Center.

Main Work

Integration and analysis of information for plant pests detection and monitoring

The main focuses of our research are (i) detection and monitoring of key insect pests, (ii) development of crop protection techniques, and (iii) estimation of crop loss caused by pests and assessment of efficiency of pest control measures.

We are conducting the following research projects: (i) thrips and whitefly transmitted plant viruses, (ii) field distribution of key insect pests and the estimation of crop losses they caused, and (iii) monitoring, integration and analysis of the information regarding the occurrence and distribution of plant pests.

Research on toxicology, efficacy and application of pesticides

The researches in our laboratories span fundamental studies and practical application of pesticides. In the aspect of pesticide resistance, we have established a database of basline sensitivity for plant pathogenic fungi and agricultural insect pests. Our studies also extend to the cross resistance of the pesticides among the plant pathogenic fungi and agricultural insect pests. These help us to build a management model on pesticide resistance. It would prolong the usage life of new pesticides and avoid the excessive use of chemical pesticides in the fields. These researches will provide useful information for integrated disease management in the fields.
On the other aspect, by way of the studies on cross resistance of the pesticides, these could help to evaluate the model of alternate use of pesticides and to mitigate the appearance of resistance populations of plant pathogenic fungi and agricultural insect pests in the fields.
Our long-term research goal will be concentrated on the mechanisms of pesticide resistance as an important basis for pesticide management in the future.
In addition, our division also works for the extension uses of pesticides in accordance to the requirements from other agricultural research institutes and district extension stations. Since the year of 2010, 2,902 cases have been assessed. The approved pesticides and their usages were authorized officially and provided to the farmers for the control of crop pests. It is very helpful to solve their needs of pesticides.
