PRODUCT INFORMATION

Spear is a Suspension Concentrate formulation. The active ingredient contained in Spear is active by contact on all mite development stages. However, mite juvenile stages are often more susceptible than adults. Spear is also effective against whitefly nymphs, plus it has a significant effect on the otherwise difficult to control pupal stage. Make applications to coincide with early threshold level in developing mite population. Spear can be applied by air, ground equipment, or through chemigation. However, thorough coverage of all plant parts is required for optimum performance. Evaluate the performance of Spear 4 - 10 days following application.

RESISTANCE MANAGEMENT

For resistance management, Spear contains a Group 23, lipid biosynthesis inhibitor (LBI) insecticide/acaricide. Any insect/mite population may contain individuals naturally resistant to Spear and other Group 23 insecticides/acaricide. The resistant individuals may dominate the insect/mite population if this group of insecticides/acaricides are used repeatedly in the same fields. Appropriate resistance-management strategies should be followed. To delay insecticide/acaricide resistance, take the following steps: • Rotate the use of Spear or other Group 23 insecticides/acaricides within a growing season, or among growing seasons, with different groups that control the same pests. • Use tank mixtures with insecticides/acaricides from a different group that are equally effective on the target pest when such use is permitted. DO NOT rely on the same mixture repeatedly for the same pest population. Consider any known cross-resistance issues for the targeted pests between the individual components of a mixture. • In addition, consider the following recommendations provided by the Insecticide Resistance Action Committee (IRAC): - Individual insecticides/acaricides selected for use in mixtures should be highly effective and be applied at the rates at which they are individually registered for use against the target species. - Mixtures with components having the same IRAC mode of action classification are not recommended for insect resistance management. - When using mixtures, consider any known cross-resistance issues between the individual components for the targeted pest(s). - Mixtures become less effective if resistance is already developing to one or both active ingredients, but they may still provide pest management benefits. - The insect/mite resistance management benefits of an insecticide/acaricide mixture are greatest if the two components have similar periods of residual insecticidal activity. Mixtures of insecticides/acaricides with unequal periods of residual insecticide/acaricide activity may offer an insect/acaricide resistance management benefit only for the period where both insecticides/acaricides are active. • Adopt an integrated pest management program for insecticide/acaricides use that includes scouting, uses historical information related to pesticide use, crop rotation, record keeping, and which considers cultural, biological and other chemical control practices. • Monitor after application for unexpected target pest survival. If the level of survival suggests the presence of resistance, consult with your local university specialist or certified pest control advisor. • Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or IPM recommendations for the specific site and pest problems in your area.

APPLICATION INSTRUCTIONS

For all insects, timing of application should be based on careful scouting and local thresholds.

Foliar Spray Applications

Foliar applications may be made using properly calibrated ground sprayers, fixed- or rotary-winged aircraft or through properly designed, sprinkler-type, chemigation equipment (See CHEMIGATION SYSTEMS section). Thorough and uniform coverage of plants, with direct contact of the spray mixture to the target pests, is required for satisfactory control

DO NOT apply where thorough coverage of plant is not possible. Applications made with less than thorough coverage may result in slower activity and/or less overall control from a single application than an application made with higher gallonages. Ground applications must be made in a minimum of 10 gallons/A.

Aerial applications must be made in a minimum of 5 gallons/A. Aerial applications made to dense canopies may not provide sufficient coverage of lower leaves to provide pest control. Higher labeled rates of Spear may be necessary for aerial applications. DO NOT apply directly to bodies of water. Time applications to allow sprays to dry prior to rain or sprinkler irrigations.

Chemigation applications

(See CHEMIGATION SYSTEMS section) must be made as concentrated as possible. For best results apply at 100% input/travel speed, for center pivots or 0.10 inch (2,716 gallons) up to 0.15 inch (4,073 gallons) of water/A, for other systems. Higher labeled rates of Spear may be necessary for chemigation applications. For low growing berries in Crop Group 13-07G, carrots, leafy green vegetables in Crop Group 4A, fruiting vegetables in Crop Group 8, cucurbits, and leafy brassica greens, applications using mechanically-pressurized handguns are prohibited.

Irrigation Timing

If irrigation is used, conduct irrigations efficiently to prevent excessive loss of irrigation waters through runoff. Time the applications to allow sprays to dry prior to rain or sprinkler irrigations. Allow at least 24 hours between application of product and any irrigation that results in surface runoff into lakes, reservoirs, rivers, permanent streams, marshes, potholes, vernal pools, natural ponds, estuaries, or commercial fish farm ponds.
