Le riz est la source de moyens de subsistance pour des centaines de millions de ménages dans le monde entier. Plusieurs pays asiatiques et africains dépendent fortement du riz comme source de nourriture et de devises ainsi que des recettes publiques. La production mondiale de riz doit augmenter de 36 % d'ici 2025 pour nourrir environ 4 milliards de consommateurs de riz. Mais la production de riz est limitée à la fois par des stress biotiques et abiotiques dont les insectes nuisibles ont causé à eux seuls environ 25 % de pertes. Le porte-feuilles de riz est considéré comme le deuxième insecte économiquement important après le foreur de la tige. De toutes les méthodes de lutte contre les insectes, la plantation de variétés résistantes aux parasites est la plus efficace. Des études biochimiques seront utiles pour confirmer l'antibiose physiologique du nouveau matériel génétique. Les facteurs météorologiques sont les principales causes régulatrices des populations d'insectes nuisibles dans des conditions de terrain. Une protection efficace des cultures fait partie intégrante des efforts visant à augmenter et à maintenir le riz, les rendements O. sativa. De nombreuses organisations nationales et internationales et groupes d'agriculteurs font la promotion de la lutte intégrée contre les parasites. L'IPM utilise des variétés résistantes aux parasites et des bases biochimiques de résistance et c'est pourquoi peut fournir d'énormes avantages aux riziculteurs.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Rice is the source of livelihood for hundreds millions of households around the Globe. Several Asian and African countries are highly dependent on rice as a source of food and foreign exchange as well as government revenue. Global rice production must increase by 36 per cent by 2025 to feed estimated 4 billion rice consumers. But the rice production is limited by both biotic and abiotic stresses of which insect pests alone caused about 25 per cent losses. Rice leaf folder is considered second economically important insect after the stem borer. Of all insect control methods, the planting of pest resistant varieties is the most effective. Biochemical studies will be helpful in confirming the physiological antibiosis of the new germplasm. Weather factors are the major regulating causes for the insect pest populations under field circumstances. Effective crop protection is an integral component of efforts to increase and sustain rice, O. sativa yields. Many national and international organizations and farmer groups are promoting Integrated Pest Management. IPM uses pest-resistant varieties and biochemical bases of resistance and that's why can provide enormous benefits to rice farmers. 240 pp. Englisch. N° de réf. du vendeur 9786135846041
