The photo-degradation products are synthetically produced. The composition is provided as a controlled release composition. (I) or (II) are: microencapsulated, preferably with polyurea; or complexed, preferably with a cyclodextrin e.g. alpha , beta , gamma cyclodextrin and their derivatives. The Bt toxins are one or more of Cry1Aa, Cry1Ab, Cry1Ac, Cry2A, Cry2Ab, Cry1A and Cry1F, Cry 3A, Cry4, Vip, and /or Vip3A. (II) is 5-(2-(2-butoxy-ethoxy)-ethoxymethyl)-6-propyl-benzo(1,3)dioxole (preferred), 5-(2-(2-butoxy-ethoxy)-ethoxymethyl)-benzo(1,3)dioxole, 5,6-bis-(2-(2-butoxy-ethoxy)-ethoxymethyl)-benzo(1,3)dioxole, 5-(2-benzyloxy-ethoxymethyl)-6-propyl-benzo(1,3)dioxole, 5-(2-(2-butoxy-ethoxy)-ethoxymethyl)-6-butyl-benzo(1,3)dioxole, 5-(2-(2-butoxy-ethoxy)-ethoxymethyl)-6-hexyl-benzo(1,3)dioxole, 5-(2-(2-butoxy-ethoxy)-ethoxymethyl)-6-propyl-indan, 5-(2-(2-butoxy-ethoxy)-ethoxymethyl)-2,3-dihydro-benzofuran, or 6-(2-(2-butoxy-ethoxy)-ethoxymethyl)-7-propyl-2,3-dihydro-benzo(1,4)dioxine.R = not defined.Preferred Method: (A) is contacted to the pest: at the same time as the Bt toxin; before the Bt toxin; or after the Bt toxin. (A) is applied directly to the pest, applied to the surroundings of the pest, applied to the plant, or two or more of these steps. (A), Bt toxins and further non-Bt insecticides are: contacted to the pest simultaneously; or contacted to the pest within a 1 hour, 2 hour, 3 hour, 4 hour, 5 hour, 6 hour, 12 hour, 18 hour, 24 hour, 36 hour, 48 hour, 72 hour, 96 hour, 120 hour, 240 hour, or 360 hour period of each other. (A) contacts the pest at least 1 hour, preferably 360 hours before the Bt toxin(s). (I) or (II) and their salts or solvates are exposed to UV light, e.g. sunlight. (I) or (II) and their salts or solvates are degraded in the presence of oxygen and/or moisture. (I) or (II) are exposed to light for greater than 0 hours, preferably at least 360 hours. The degradation of (I) or (II) occurs by one or more of: (i) degradation of one or more of the side chains on the benzodioxole ring; (ii) oxidation of one or more of the side chains on the benzodioxole ring; (iii) hydrolysis of an ether linkage in one or more side chains; (iv) further oxidation, hydrolysis or cleavage of any derivative formed in (i)-(iii). In the method: no non-Bt insecticides, pesticides and/or insecticide synergists are administered within 1 hour, 2 hours, 4 hours, 8 hours, 12 hours, 18 hours, 24 hours, 2 days, 4 days, 7 days, or 2 weeks of applying the composition; and/or no non-Bt insecticides, pesticides and/or insecticide synergists are applied 1 hour, 2 hours, 4 hours, 8 hours, 12 hours, 18 hours, 24 hours, 2 days, 4 days, 7 days, or 2 weeks before applying the composition. Preferred Definitions:    R1-R3 = H, propyl, n-butyl, or CH2OR4, where R1-R3 are all the same, they are not H;    R4 = -(CH2CH2O)2-R5;    R5 = 2-4C alkyl, phenyl or tolyl; and    n = 1 or 2.    ACTIVITY - Insecticide; Arachnicide.    MECHANISM OF ACTION - Proteolytic enzyme modulator.    ADMINISTRATION - Application of (A) is by foliar spraying. No dosage details given.
