Nitrogen and Potassium Fertilization Modulate Dalbulus maidis (HEMIPTERA: CICADELLIDAE) Abundance and Corn Stunt Disease Severity

Agriculture
Corn stunt complex, transmitted by the corn leafhopper (Dalbulus maidis), poses significant yield risks to corn production. This study evaluated the effects of two corn hybrids and top-dressed nitrogen (N) and potassium (K) fertilization on D.

Physicochemical, in vitro, and in vivo compatibilities of fungicides and mycoinsecticides used in maize crops

Biological Control
Given the operational advantages and temporal coincidence of diseases and pests, tank mixtures of fungicides with mycoinsecticides are commonly verified in cornfields practices in Brazil. Thus, we examined the compatibility of Beauveria bassiana isolates

Management and Control Strategies for the Corn Leafhopper (Dalbulus maidis): A Systematic Literature Review

Asian Plant Research Journal
The corn leafhopper (Dalbulus maidis), vector of the corn stunt complex (Spiroplasma kunkelii, Phytoplasma, and MRFV) in corn (Zea mays L.), causes losses of up to 100% in the crop. This review aimed to analyze the limitations of current control methods and the potential of integrated strategies.
