Low volume (LV) aerial and ground sprays have become an important method of application in Florida citrus. We continue our evaluations of LV application of 435 horticultural mineral oil (HMO) which has shown promising results the last 3 years. This report documents updated results from the fifth trial begun on February 2011 in a 10.9 acre plot of ‘Valencia’ orange in Lee County. The efficacy of low volume spray spray of 435 horticultural spray oil (HMO) with the Grower Standard and an Untreated control are being compared. This trial is the first with sufficiently high ACP populations to assess the ability of LV oil sprays to provide suppression. Five sprays of 435 oil (13, 29 Jul @ 4gal/ac; 30 Jun 2, 22 Sep @ 2gal/ac) have been completed since the last report. Plots designated for the Grower Standard received 20 oz of Dimethoate + 2gal 435 oil on 30 June and 4oz of Delegate + 4gal 435 oil on 29 July. Mean adult psyllid populations over the last 3 months were 0.35 +/- 0.037,0.19+/-0.024 and 0.031+/-0.009 for the Grower Standard, Oil, and Untreated Check respectively. These values were all statistically different. Thus, the low volume oil treatments are suppressing ACP but not as effectively as the Grower Standard. Canker has worsened in the grove, so we added citrus leafminer (CLM) assessments to determine if treatments are providing some control. Pheromone traps were placed in the grove on 24 May a second damage assessment of leaves using a modified Horsfall Barratt scale will be conducted in late Oct. CLM control requires precise application timing on emerging flush to be effective, so there is considerable interest in aerial application to manage this pest. Therefore, we evaluated ground and aerial applications of the insect growth regulator methoxyfenozide (Intrepid 2F), and a ground application of spinetoram (Delegate WG), an analog of spinosyn A which is derived from actinomycete bacteria. Both products are selective with low vertebrate toxicity and widely used for CLM control. Treatments were applied 7 July in an 94 acre block divided into 12 large plots using a replicated complete block design with 4 treatments and 3 replicates. Pheromone traps were used to monitor CLM populations within all plots before and after application. Intrepid 2F treatments, regardless of application method, showed significantly less damage than the Delegate treatment or the untreated check on 20 July. On 29 July, significantly less damage was observed in response to the Intrepid2F ground and Delegate treatments compared to the untreated check. An assessment 2 months later showed less CLM damage in the Intrepid ground and Delegate plots, with trap captures lowest for Intrepid ground applications. Therefore, significant control was obtained with the aerial application of Intrepid, but not as much or as enduring as with the ground application.
