Tolfenpyrad
Chemical Details on TolfenpyradChemical Name: 4-chloro-3-ethyl-1-
methyl-N-[4-p-tolyloxy)benzyl] pyrazole -5-carboxamide
Empirical Formula: C21H22Cl N3O2Molecular Weight: 283.9Code Number: NAI-2302
Insects ControlledHemiptera, Coleoptera, Diptera,
Lepidoptera, Thysanoptera, and AcarinaPoisoning by ingestion; contact activity;
anti-feeding activity against lepsTarget Crops:
Vegetables, Cucurbits, Cole CropsFruits & NutsSelected row cropsOrnamentals
Efficacy Trials
Use rate 0.137 to 0.274 lb. a.i/acre (153-307 grams ai / hectare)
14 – 27 oz/a (15% EC and 15% SC formulations)
Alternative mode of action useful against numerous vegetable and fruit/nut pests
U.S. Registration Timeline

NAI-2310 (FLUBENDIAMIDE)
New generation of chemistry active against Lepidoptera at low rates
Discovered by NNC and marketed by NNC and Bayer
Registered in Japan as Phoenix
FLUBENDIAMIDEProduct Characteristics
Flubendiamide (NAI-2310) Target Mkts: TNV, Vegetables, Cotton Chemistry: Substituted phtallic acid diamide MOA: Ryanodine receptor modulator Ingestion by insect results in immediate cessation
of feeding Contact (not systemic in plants and has only
limited translaminar movement) Rates: 15-140 gms ai/hectare

of NNI-0101 treated insects
NNI-0101 shows two distinct effects on aphids; 1. Rapid response of abnormal behavior (insect dispersion, feeding cessation)2. Slow lethal action
Possible IR-4 InterestsOnion thrips (PCR submitted)Aphid, Thrip, Whitefly, Mealybug and Scale control on ornamentals
Rapid cessation of whitefly and aphid feeding reduces transmission of viruses vectored by these pests on important fruit and vegetable crops
