The THINVERT Application System for helicopters and fixed wing aircraft:

• Applies economical low volume sprays of 1 to 4 gal/A.
• Controls spray drift.
• Controls evaporation of spray droplets.
• Combines a superior spray fluid with an innovative nozzle design.

The THINVERT Nozzle is a precision application device which makes small, uniform spray droplets with a minimum of fine, driftable particles.

Droplet sizes of 300 to 500 micrometers provide effective control of vegetationor insect pests with economical, low spray volumes.

THINVERT Nozzles can be used on TVB Thru Valve Boom sprayers and can be adapted to most conventional spray booms.

THINVERT Deposition Aid Aero Concentrate provides good coverage of of plant surfaces while using economical, low spray volumes of 1 to 4 gallons per acre.

Because THINVERT spray droplets are wrapped in a thin film of oil, they do not evaporate and shrink in diameter even when released high in the air.

Mixing and Application Instructions:

CHOPPER herbicide may be applied aerially using helicopters for preparation of forest sites prior to planting one of the southern pines. For best results with the THINVERT Application System, apply 64 ounces of CHOPPER herbicide in a mixture of THINVERT Aero Concentrate and water at a spray volume of 3 gal/A. Apply using THINVERT nozzles mounted on a TVB Thru Valve Boom or other suitable streamlined spray boom.

Preparation of a THINVERT Emulsion:

Add one part THINVERT Aero Concentrate to the mix tank. Add two parts water to the THINVERT Concentrate, while agitating vigorously. Continue agitation while adding the required amount of CHOPPER herbicide to the THINVERT mixture.

Since THINVERT contains a precise combination of emulsifiers and surfactants, do not add additional surfactant to the spray mixture.

Application:

To obtain drift control with the THINVERT sprays and utilize the low volume characteristics of the System, it is necessary to use THINVERT nozzles or TVB .020" wedge nozzles. Use an aerial applicator familiar with the use of THINVERT sprays and with mounting and operating THINVERT spray nozzles.

Make applications in the spring of the year after full leaf expansion of the target weed or brush has occurred and before formations of fall colors. Spring applications provide optimum brownour for site preparation burning.

Read complet elabel of CHOPPER herbicide before applying herbicide to forest sites. Observe all directions and precautions on the CHOPPER herbicide label.

Field Results with other THINVERT Aerial Sprays:

Herbicide Applications - Forestry

Roundup herbicide was applied at 1.3 qts/A in THINVERT at a total volume of 1 gal per acre using a TVB Thru Valve Boom equipped with THINVERT Nozzles to control hardwood vegetation in spruce and fir regeneration. Applications were made in July 1993. Results were comparable to conventioanl applications at 10 gal/A.

Insecticide Applications - Sugar Cane

On target application is important in sugar cane applications to reduce pesticide deposition to the water in furrows and drainage ditches.

Furadan Insecticide was applied to control sugar cane borers in August 1993. Furadan was four times more effective when applied in THINVERT than in conventional sprays. The THINVERT sprays also reduced insecticide deposition in adjacent water.
