The Taltar Xtra bag does not specifically list setting for the Scotts Speedy Green 3000, but it does list the Scotts SpeedyGreen 2000 and its spreader settings. If this is what you meant, or those two spreaders are compatible with settings, you can use setting 2 3/4 for putting out 1.15 lbs per 1000 sq/ft, 5 1/4 for 2.3lbs per 1000 sq/ft, or 9 for putting out 4.6 lbs per 1000 sq/ft. Otherwise if your settings do not match up, you would want to calibrate your spreader for the product. Here are instructions on how to calibrate your spreader.
How to calibrate your spreader:
Almost all fertilizers, herbicides, insecticides, etc have treatments in amounts of so much product per 1000 square feet. So if you can figure out what your walking speed is then you know anytime you apply any product that calls for so much of it per 1000 square feet, you always set your spreader on this setting. You can calibrate this by marking off a 1000 square foot (10 x 100) area and placing the required amount of product in pounds in the spreader. Start with a low setting and start walking your marked off area at a normal pace. You can adjust as you go and find the basic setting for you to apply the product over a 1000 square feet.
Talstar XTRA Granules will last up to 4 months so you can apply once a quarter.
Using Talstar XTRA Granules to achieve acceptable control of mole crickets is difficult because preferred grass areas are subject to continuous invasion during early spring by this extremely active stage. Application can be made at any season and should be applied as late in the day as possible and be watered in with up to .5'' of water immediately after treatment. If the soil is not moist, then it is important to irrigate before application to the mole crickets closer to the soil surface where contact with the insecticide will be maximized. Please see the product label for complete application instructions.
Talstar P has a monthly residual on the exterior areas where the Talstar XTRA Granules will last 2-4 months in the lawn. The benefits of treating with the liquid solution is that you could treat the interior cracks and crevices quarterly for pest control as well as on the siding and around entry points (ie window frames, door frames, garage, etc).
According to the manufacturer, Talstar cannot be used in horse pastures for any purpose.
Extinguish Plus Fire Ant Bait would be a better choice for you. Extinguish plus can be used on pasture land and there are no grazing restrictions for companion animals. Below you will see the grazing info available on the Extinguish Plus product label. Extinguish Plus combines the power of hydramethylnon with an insect growth regulator (IGR) to kill fire ant workers and prevent queens from laying fertile eggs. The result is complete fire ant colony control. Extinguish Plus Fire Ant Bait is best used in the spring or early fall, or whenever fire ants are active. The ants will feed off Extinuish Plus and spread the bait throughout the entire colony, halting the infestation within weeks. Extinguish Fire Ant Bait can be used indoors and outdoors on lawns, pasture land, rangeland, landscaped areas, and golf courses.
EXTINGUISH PLUS may be applied to grass forage
(pastures and rangeland) for the control of fire ants
only in the following states: Alabama, Arkansas,
Florida, Georgia, Louisiana, Mississippi, New
Mexico, North Carolina, Oklahoma, South Carolina,
Tennessee, Texas, and Virginia. Use on grass forage
(pastures and rangeland) in states other than those
listed is unlawful. See Outdoor Use table for
application directions. Do not exceed 8 pounds per
acre per year or more than 4 times a year, with a
minimum re-treatment interval of 90 days. Do not bale
and cut treated pastures and rangelands for 7 days
following application. These cutting and baling hay
restrictions for pasture and rangeland do not apply
when the treated pasture and rangeland is used solely
to support COMPANION ANIMALS (e.g., horses,
llamas, etc.). Companion animals grazed on treated
areas cannot be used for food or feed. EXTINGUISH®
PLUS may be used on uncultivated, agricultural, nonfood
crop and non-agricultural land.
Talstar Xtra with Verge is safe for use on all lawns including St Augustine.
We recommend using Talstar XTRA to treat for a sod webworm infestion. This innovative granule is approved for broadcast lawn, perimeter and mound treatments, making it a versatile and valuable component of your ongoing pest control program. And because it achieves impressive results even at low application rates, Talstar XTRA granular insecticide is an excellent, cost-effective solution for fast-acting, long-lasting protection. The residual protection of Talstar XTRA granular insecticide is proven to remain effective for at least four months. When treating for sod webworms you want to use 1.15 to 2.3 lbs/1000 sq ft or 50 to 100 lbs per acre.
When using Talstar Xtra Granules, we generally recommend that you use between 2-3 depending on how quickly you walk. This can be used at as high as a 5 as well for the higher concentration. Be sure to water this product in after application.
Talstar XTRA Granules should be applied in early spring immediately or prior to egg hatch for treatment of mole cricket nymphs. The nymphs are located near the surface of the soil.
Talstar XTRA Granules are not labled for vegetable gardens. We cannot advise for you to consume anything from the garden after Talstar Xtra was applied. Instead you could use something like Sevin Lawn Insect Granules. If a granule is not necessary, another great option would be the Fertilome Triple Action Plus which can be sprayed in and on the garden for control of insects and vegetable diseases, and the food can be harvested the same day.
