In recent years, with the continuing burden of increasing development and registration costs, the agricultural community has been facing the loss of a number of products from its portfolio of insecticides. Furthermore, as different governments enact upgrades to their regulatory procedures or bring in tough new re-registration laws, there will be additional pressure on minor products that fit niche markets and specialty use opportunities, some of which are of significant importance to cotton growers. This trend affects the whole agricultural industry, but is particularly noticeable in cotton where perhaps the broadest range of products is used on a wide variety of pests in cotton producing countries around the world.
It is encouraging, therefore, to see that despite the increasing costs that the multi-national agricultural chemical companies are incurring to support their international registrations, there has not been a time in recent years when so many new insecticide developments are finding their way into the hands of the cotton grower. These new developments cover new chemistries with novel modes of action, both contact and systemic, such as the nicotinyls, pyrroles, phenyl pyrazoles, amino triazinones and the quinazolines. In addition there are several new insect growth regulator products, both benzoyl phenyl ureas as well as novel structures, hormone analogs and a range of new products and improvements in the field of biologicals and natural products. In terms of resistance management, such developments could not come at a better time to fit into integrated programs around the world. Some of these new products will undoubtedly find utility in helping overcome control problems due to resistance.
These new developments, from a wide variety of agricultural chemical companies, and their potential for the control of various pests around the world, are reviewed. Opportunities that some of these discoveries might offer in terms of resistance management are also discussed.
It is clear from the above that there is significant potential for the expansion of the global arsenal of new insecticide products. Not all the products discussed will end up with cotton registrations in all or even some countries. Different governments regulate the registration of new pesticides in different ways, thus certain products may mature with disjointed use patterns on a global basis. Some others, such as the new chemistries that possess novel modes of action, may very well obtain registration in all the major cotton markets. Most of the products discussed will find great utility in the handling of resistance concerns, adding new opportunities for the development of more effective management programs.
After the paucity of new developments over the last decade, we are entering into an exciting future of integrated pest control that bodes well for the long term survival of global agriculture.
