Before these invasions, a dozen arthropods and four common diseases, some causing significant yield losses, had been recorded on cassava. This chapter considers the cases of P. manihoti, M. tanajoa, Stictococcus vayssierei, Zonocerus variegatus and four main diseases: cassava bacterial blight, cassava anthracnose, cassava leaf spots and cassava root and stem rots (the viral diseases being treated in Chapter 5 of this book). This narrow selection is justified, as proven control methods – biological, cultural and resistance breeding – can be adapted to control other cassava pests.","brand":"Dr Muaka Toko","offers":[{"title":"Default Title","offer_id":48281311871227,"sku":"9781838797546","price":32.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/3917\/9771\/files\/CoreSourceHub_c32d620e-d8fb-441c-bdb8-b01b36c03dbe.jpg?v=1771306016","url":"https:\/\/indiepubs.com\/products\/identifying-and-managing-plant-health-risks-for-key-african-crops-cassava-9781838797546","provider":"IndiePubs","version":"1.0","type":"link"}
