Abstract
Description
[Technical Field]
[0001] The present invention relates to compounds having nematicidal activity, agricultural compositions thereof, and the use of such compounds to treat or control parasitic nematodes or nematode infestations in agricultural crops. [Background technology]
[0002] Nematodes are active, flexible, elongated organisms that live on moist surfaces or in liquid environments, including water films in soil and the moist tissues of other organisms. Many species of nematodes have evolved to be highly successful parasites of plants and animals, causing significant economic losses in agriculture. Nematodes are known to affect the yield, growth, and health of crops and plants. Physiological changes in the roots of host plants caused by larval and / or adult nematodes can lead to the formation of galls, which cause the destruction of the vascular system in the plant's roots. Root growth may cease completely, and an inadequate supply of water and nutrients provided by the reduced root system can lead to whitening and / or wilting of leaves and stunted growth, all of which can result in low yield or death. In addition, nematodes can cause physiological effects that increase the susceptibility of plant roots to bacterial and / or fungal attack, including bacteria and / or fungi that the plant would otherwise tolerate. Such attacks can lead to widespread secondary rot and decay. Control of plant parasitic nematodes is therefore crucial to achieving high crop efficiency. Summary of the Invention [Problem to be solved by the invention]
[0003] Despite available treatments, nematodes continue to pose a problem due to the widespread development of resistance to anthelmintics in nematode parasites. There remains a need for new compounds that are more effective, cheaper, less toxic, environmentally safe, or have a different mechanism of action. [Means for solving the problem]
