Plant-parasitic nematodes are a significant factor limiting potato production and tuber quality in several regions where potato is produced. Overall, parasitic nematodes alone cause an estimated annual crop loss of $ 78 billion worldwide and an average crop yield loss of 10-15%. As a result, sustainable food production and food security are directly impacted by pests and diseases. Degrading land use with monocultures and unsustainable cropping practices have intensified problems associated with plant pathogens. Proper identification of nematode species and isolates is crucial to choose effective and sustainable management strategies for nematode infection. Several nematode species have been reported associated with potato. Among those, the potato cyst nematodes Globodera rostochiensis and G. pallida, the root-knot nematode Meloidogyne spp., the root lesion nematode Pratylenchus spp., the potato rot nematode Ditylenchus destructor and the false root-knot nematode Nacobbus aberrans are major species limiting potato yield and leading to poor tuber quality. Here, we report a literature review on the biology, symptoms, damage and control methods used for these nematode species.

Off-season tomatoes produced in Southeast Brazil in Spring-Summer crops are highly valued, but crop yield is limited by high rainfall and temperatures. To overcome this situation and make off-season tomato crops more profitable, they can be grown under controlled conditions in protected cultivation systems. In addition, tomato yield and quality can be improved by adequate levels of potassium (K) fertilization. The present study evaluated the off-season (Spring-Summer) yield of tomato crops grown in the field or in protected systems (hydroponics and fertigation) using different levels of K application.
