PCR Reason for Need: Tomato russet mites (Aculops lycopersici) are much smaller than the two-spotted spider mite, and are virtually undetectable with the naked eye. A high magnification hand lens such as 50 to 100X or microscope is required to see and identify these mites. For this reason, infestations can go undetected until significant damage to the crop is observed. Currently there are a very limited number of miticides registered for the control of tomato russet mites that are also “soft” on the benefical control agents (BCAs). The need for products that can help manage the pest and not negatively impact BCAs are urgently needed.IR-4 is conducting residue work and efficacy work on thrips under PR# 13403 for isocycloseram [4/23]; follow same use pattern if project gets prioritized.Tomato russet mites (Aculops lycopersici) infestations can go undetected until significant damage to the crop is observed [AL: 87/23]

Artificially infested, four-week old, greenhouse grown tomato cv. Jolene, were treated via foliar spray applications at 50 gal water/ A, when a threshold greater than 20 mites per leaf was observed. Representative tomato leaves were collected and tomato russet mites (Aculops lycopersici) were counted. On average across assessment dates, all treatments significantly reduced mites per leaf compared to the negative control and no phytotoxicity was observed.
Magus/ fenazaquin (36 fl oz/A applied once), MBI-306/ Burkholderia spp. strain A396 (20 fl oz/A, applied 3 times with 7 day retreatment interval (RTI)), EpiShield/ Peppermint oil, clove oil, and sodium lauryl sulfate (12 fl oz high and 9 fl oz low rate/A, applied 3 times with 7 day RTI) and Plinazolin Technology 200SC/ isocycloseram at a high rate (6.1 fl oz/A applied 3 times with 7 day RTI) showed the greatest average percent reduction in mites per leaf compared to control and the commercial standard (79, 78, 54% for low to 70% for high treatment rate, and 64% respectively).
The commercial standard Akari 55C/ fenpyroximate (2 pts/A, applied 2 times with 14 day RTI) reduced mites per leaf by 54%, while TetraSan 5WDG/ etoxazole (applied 3 times with 7 day RTI) and Pylon/ Chlorfenapyr (13 fl oz/A applied 3 times with 7 day RTI) achieved similar reduction levels (54 and 53 % respectively). TetraCURB MaX/ castor oil, rosemary oil, clove oil, and peppermint oil (1% v/v applied 3 times with 7 day RTI) and Plinazolin Technology 200SC at a low rate (4.1 fl oz/A applied 3 times with 7 day RTI) also reduced mites per leaf compared to control (42 and 34% respectively).
