Dow AgroSciences has a long history of proactive insecticide resistance management efforts. In our experience, the key to managing resistance is to reduce selection pressure on any one mode-of-action by convincing farmers to rotate among effective insecticide products with different modes of action and to use only the number of insecticide applications required for effective Integrated Pest Management (IPM). To accomplish this, farmers may need to use non-chemical control methods and to rotate to insecticide products that are effective but may not provide the highest levels of control. Integrating rotation of effective insecticides with other IPM techniques can provide high quality and quantity of the harvested crop. We will share our experience managing spinosyn resistance with a series of best management practices for western flower thrips (Frankliniella occidentalis Pergande) and our resistance management recommendations for ISOCLASTTM (sulfoxaflor), our new insecticide for control of sap-feeding insect pests. Dow AgroSciences is an active member of the IRAC (Insecticide Resistance Action Committee) and strongly supports the placement of IRAC mode-of-action group numbers on insecticide product labels. This simple approach greatly facilitates effective product rotation. Resistance management is critical to maintaining the effectiveness of the current arsenal of conventional insecticides and transgenic insect-resistant crops for as long as possible. Responsibility for resistance management is shared between manufacturers, formulator-distributors, retailers, influencers (universities, government), and farmers. It is up to all of us to make sure all stakeholders, and especially farmers, fully understand the benefits associated with insecticide resistance management (IRM) programs and the consequences associated with the resistance development in insect pest populations. ™ Trademark of The Dow Chemical Company ('DOW') or an affiliated company of Dow.

Highland agriculture is a kind of specified agricultural term based on altitude and meteorological characteristics and their main crops are seed potato and vegetables. These crops are only cultivated in summer season when insect pests are most dynamically attacking such as diamondback moth (DBM, Plutella xylostella) and aphids son on. Aphids, insect virus vector, are really annoying factor, particularly in seed potato. Furthermore, these insect pests formed small sub-population or colony based on small field area. For instance, green peach aphid (GPA, Myzus persicae) populations’ genetic backgrounds and insecticide susceptibilities were different even in the same Pyeongchang area. Therefore, we suggested that highland agriculture should adopted IRM strategy for the control of insecticide-resistant aphids. First. Monitoring of annual fluctuation of insect population using traps for more effective monitoring. Second. Performing the insecticide resistant monitoring patch by patch or field using high throughput molecular diagnosis for more accurate monitoring. Third. Establishing the insect pest management program based on these results. We will deeply discussed practical monitoring results and IRM strategy in highland agriculture.
