DOCTRINE®

Specifications

Doctrine® is an insecticide in granule formulation with contact and stomach action which is used to control pests in corn, vineyard, tomato and pepper. It is effective against all stages of pest larvae and eggs of some species. Doctrine® acts by blocking the sodium channels of the insects’ nerve cells; shortly after spraying, the pest’s nutritional and other activities are ended or significantly reduced. Pests die within 24-60 hours. Doctrine® is not affected by rain starting after the applied product dries on the plant; so there is no need to repeat application.

Method Of Application

Beet armyworm in corn: Spraying is done immediately if field check reveals 2 larvae on average per plant. Do not apply Doctrine® more than 3 times in the same location during the same season.

Grapevine moth: Sprayings can be repeated up to 6 times for table grapes and up to 3 times for wine grapes during a season. Applications can be made using a tractor-fitted hydraulic sprayer or a back sprayer. For the best results, spraying should be done when the eggs hatch. Spraying in this period also provides protection against eggs that haven’t hatched yet and against new eggs. Spraying should be repeated at 10-14 day intervals if necessary, depending on pest intensity and the number of flying imagos. Sprayings are done according to a forecast and warning system. If the number of moths caught in traps has reached peak and started to fall; accumulated degree-days reach 120 degree-days in the first generation, 520 degree-days in the second generation and 1047 degree-days in the third generation; and if, from a phenological perspective, first generation corresponds to the flower bud stage, second generation to unripe grape and third generation to start of sweetening; eggs are checked and spraying is decided according to hatching. One spraying is done for each generation.

Cotton leaf worm in pepper and tomato: For optimum results, spraying should be done during the period when the eggs hatch. Vegetable areas should be checked diagonally and pest management should be started if 1-2 newly hatched egg bundles or 4-5 larvae are seen in 100 plants. Timing should be chosen carefully since better results are obtained if spraying is done before the larvae scatter. Spraying should be repeated at 10-14 day intervals if necessary, depending on pest intensity in the season. Doctrine® is effective against the pest’s larvae.
