Pest control rating system when used at recommended rates: 1 = excellent, 2 = good, 3 = fair, 4 = poor, -- = not registered or efficacy unknown

Fruit finish, when used as recommended, is excellent for all products except good for diazinon and fair for M-Pede.

BMSB = brown marmorated stink bug; CM = codling moth; ERM = European red mite; GA = green aphids; GFW = green fruitworm; LR = leafrollers; OFM = Oriental fruit moth; PC = plum curculio; PLBM = pearleaf blister mite; PP = pear psylla; PRM = pear rust mite; SJS = San Jose scale; TPB = tarnished plant bug/native stink bugs; TSM = twospotted spider mite

a. Uppercase names are trade names; lowercase names are common names for products with more than one trade name.
b. Danitol is less effective for late season ERM control.
