FAW is a key pest of sweet corn in Florida and larvae can feed onwhorls, tassels, silks, and ears leading to a yield and grade reduction.Program approaches using rotations of insecticide mode ofaction are necessary to reduce the chances of insecticide resistance,and new chemistries are always in demand for more sustainableFAW control. This trial was conducted at the Southwest FloridaResearch and Education Center in Immokalee Florida on fourbeds, 32 inches wide, and 430 ft long on 6 ft centers that were preparedon 23 Jan 2019 and fumigated with Pichlor 60 EC on 8 Feb.Fertilizer (8-2-10) was incorporated at 100 lbs N and beds wereprovided with two drip tape irrigation lines with 8 inch emitterspacing as they were covered with black polyethylene mulch. Cornwas direct seeded on 25 Feb at 10 inch spacing with two seedsper hole and a 7-2-7 liquid fertilizer was injected through the dripusing a Dosatron over the growing season. Eleven treatments andan untreated check were assigned in an RCB design with fourreplicates. Each plot contained 35 plant spaces with 8 plant spacesleft between plots as a buffer. An untreated row of corn was in betweeneach treated row to act as a buffer. Applications were madewith a high clearance sprayer moving at 2.3 mph equipped withfour ceramic Albuz ‘yellow’ hollow cone tips each delivering 10gpa at 180 psi for a total of 40 gpa. The dates of applications andproducts applied are listed in Table 1. On 9 and 16 May, 10 earswere collected from each plot, and the number of larvae collectedwas recorded along with the number of damaged ears per plot.FAW numbers were very low in this trial.
