Lycopersicon esculentum Mill.
Southern armyworm is the most damaging noctuid pest of tomatoes in southwest Florida.
Selective synthetic and biopesticides, such as those tested here, are providing growers with control alternatives relatively compatible with biological control. The center bed in each set of 3 beds was left untreated to serve as a source of pest innoculum. The 4 treated beds were divided into plots 48 ft long to which 7 treatments were assigned in a completely randomized block design with 4 replications. Treatments were initiated after a mean of 0.2 armyworms per plant was observed on 12 plants per plot 24 Oct. Six weekly evaluations were performed starting 31 Oct to monitor damage and larvae on 6 plants per plot.
