666.01Description

The work covered by this Section shall consist of furnishing and applying designated chemicals to control certain destructive pests, namely, Armyworm, Fall Armyworm, Cutworm, Spittlebug, White Grubs and Pine Bark Beetles. PEST CONTROL 570

Because of the destructive nature of the action of these pests to trees and ground cover with the possible result of erosion and ultimate siltation of areas, control of these pests is a necessity. Both the Engineer and the Contractor have the responsibility of continually observing the planted areas for possible pest damage. The Contractor should, upon observing any of these pests, report such to the Engineer, both verbally and in writing. The Engineer will verify any reports of this type of pest and direct appropriate treatment to be taken. The following brief descriptions are provided for ease in recognizing these pests: Armyworm: A medium size caterpillar of dark green color with white stripes on sides and down the middle of the back, Size, approximately 1 inch {25 mm} in length. This worm usually feeds only at night destroying foliage. Fall Armyworm: A medium size caterpillar of dark green color with white stripes on sides and down the middle of the back with a distinctive yellow inverted "Y" on the head capsule. Size, approximately 1 inch {25 mm}. This worm will feed both day and night destroying foliage. Cutworm: A fat bodied caterpillar with a greasy appearance, color mostly greybrown or mottled on top and lighter color underneath. Size, approximately 1 to 2 inches {25 to 50 mm} in length when full grown. This worm hides during the day and feeds at night, destroying foliage. Spittlebug: Most easily identified by a frothy mass of plant juice at the forks of plant stems resembling spittle. This pest lives inside the spittle mass. White Grubs: The immature (larval) stage of June or May beetles. Length, 0.5 to 1.5 inches {13 to 38 mm}, have three pairs of legs near the head, and characteristically rest in a C-shaped position. Their heads and rear ends are brown. Green June Beetle grubs crawl on their backs with their legs up. Pine Bark Beetles: These beetles are distinguished from other bark beetles in that the rearward end of the abdomen is scooped out and spined (4 to 6 spines on each side). The southern pine beetle and black turpentine beetle have a more rounded abdomen. The black turpentine beetle is the larger of the two, being about 1/4 inch {6 mm} long . The southern pine beetle is about 1/8 {3mm} inch long. All of the pine bark beetles are roughly cylindrical and are dark brown to black.

666.02Material

The treatments to be used under this Section shall be as per the current Alabama Pesticide Handbook or Guidelines as may be issued by the Alabama Cooperative Extension Service. As new pesticide materials are approved by the State Department of Agriculture and Industries, the Bureau of Construction may allow their use upon written request by the Contractor. All chemicals shall be a product of a reputable manufacturer, processed in accordance with all State and Federal regulations for such manufacture. Restricted Use of Insecticides Whenever the State Department of Agriculture and Industries or other Federal or State agency restricts the use of any insecticide on highway right-of-way, its initial or continued use shall require the approval of the Construction Engineer. It is illegal to place herbicides in a manner that is not consistent with the requirements shown on the insecticide container labeling.

666.03Construction Requirements

The Engineer after verification of the pest occurrence and identification of the type pest shall direct the use of treatments as noted in Article 666.02 in accordance with the following: Equipment used in the application shall be designed for the application method to be used and approved by the Engineer for use. The application of pesticides shall be performed by or under the direct supervision of a licensed pesticide applicator, licensed in the area of right-of-way pest control. Uniform coverage is required. If uniform coverage is not obtained, the Contractor shall retreat the entire area in such a manner that uniform coverage is obtained. Retreatment because of uneven coverage shall be without additional cost to the State. Retreatment shall not be performed within seven days of the original treatment. All treatments shall be at the direction of the Engineer. In all treatments, dilutions of liquids and technical material dosage applied shall follow label instructions, these Specifications and be verified by the Engineer. Any change to the dilution rates of a specific chemical or the substitution of chemicals other than those meeting the requirements of Article 666.02 must have prior written approval of the Construction Engineer and any such approved change must be without additional cost to the State.
