Problem Code: Orgnc
Requesting State(s): Lloyd,Margaret (CA)
Potential Products: Entrust SC Naturalyte Insect Control; Cinnerate; Ecotrol
PCR Reason for Need: Despite growers' efforts to explore materials, they do not feel they have a clear idea of product efficacy. Product cost ranges significantly and sprays are frequent. Thrips transmit TSWV and compromise production.
PCR Details:
Study Goals: This CDFA-funded study evaluates innovative rotations of commercially available organic insecticides to find successful management programs for the control of thrips in field-grown organic tomatoes. The products that were included in the trials were: 1) Entrust SC (spinosad), 2) Trilogy (neem oil), 3) Cinnamate (cinnamon oil), 4) Ecotrol EC (rosemary, peppermint, wintergreen oil), 5) SuffOil-X (mineral oil), 6) Venerate XC (Burkholderia spp. strain A396), 7) NoFly WP (Isaria fumosorosea) [HQ: 8/25 AA].
Comments
Study Accomplishments: The researcher is currently using the data to educate organic tomato producers on research outcomes [HQ: 10/25 AA].

IS00415-22-CA012022CAUniversity of CaliforniaAlice AxtellMargaret Lloyd IS00415-22 Yes   SIGNIFICANT CONTROL OF A THRIPS INFESTATION ON ORGANICALLY GROWN TOMATOES WAS ACHIEVED ON PLANTS TREATED WITH ENTRUST SC (SPINOSAD) AT 8 FL OZ/A WHEN ROTATED WITH TRILOGY (NEEM OIL) 2% V/V, CINNARATE(CINNAMOM OIL) AT 32 FL OZ/100 GAL AND ECOTROL EC (ROSEMARY, PEPPERMINT AND WINTERGREEN OIL) AT 6 FL OZ/A COMPARED TO UTR AND ECOTROL EC ALONE. TREATMENTS WERE APPLIED 6 TIMES AS A FOLIAR SPRAY EVERY 6-7 DAYS.

TWO TREATMENTS SUFFOIL-X (MINERAL OIL, APPLIED AT 256 OZ/100 GAL) AND VENERATE XC (BURKHOLDERIA SPP. STRAIN A396, APPLIED AT 128 OZ/A) WERE TESTED AGAINST THRIPS INFESTING ORGANIC FIELD-GROWN TOMATO PLANTS AS A SOLO PRODUCT AND IN ROTATION WITH NOFLY WP (ISARIA FUMOROSEA, APPLIED AT 32 OZ/100 GAL) AND ENTRUST SC (SPINOSAD, APPLIED AT 8 OZ/A) RESPECTIVELY. A TOTAL OF 6 APPLICATIONS WERE MADE AT A RE-TREATMENT INTERVAL OF 7 DAYS. TREATMENTS WERE TANK MIXED WITH THE ADJUVANT OROBOOST AT 32 OZ/100 GAL. THE DIFFERENCES BETWEEN THE TREATMENTS AND UNTREATED PLOTS WERE NOT SIGNIFICANT. ISARIA FUMOROSEA ALTERNATED TO MINERAL OIL AND BURKHOLDERIA SPP. SHOWED SOME SUPPRESSION UNDER LOW PEST PRESSURE. BURKHOLDERIA SPP. REDUCED POPULATIONS THE MOST WHEN THEY WERE THE HIGHEST. PHYTOTOXICITY WAS NOT OBSERVED.
