S o much of success in agriculture is related to timing. The right thing just needs to be done at the right time. Things work better, and you stay out of trouble. Some technologies make timing easier than others. You can put new GrazonNext™ herbicide in the “easier” category. It also tops the “superior pasture weed control” category.

This exclusive program is reserved for products that demonstrate lower risk to the environment and to humans than the market standards. GrazonNext™ herbicide combines aminopyralid with high-quality 2,4-D for cost-effective weed control. GrazonNext is not a federally Restricted Use Pesticide, but it is subject to state restrictions on 2,4-D. In Texas, that means it still requires a license to buy or apply.

John Wilder sprays big clumps of blackberry with an effective herbicide, lots of water and a big tractor. Surmount also controls broadleaf weeds and provides soil residual activity to control weeds that germinate for weeks after spraying. “In 2006, I sprayed berry vines and persimmons and weeds I’ve never seen,” Wilder says. “It did a good job. Some of the persimmons came back, but there’s no telling how much root system is down there. They’d been mowed and mowed.” In Dow AgroSciences demonstrations, a labeled 1 percent solution of Surmount has controlled persimmon when sprayed by hand. Broadcast applications have been less effective on persimmon. Experts speculate that, for control, persimmon needs to be saturated with the herbicide solution. Use the right amount of herbicide, surfactant and water. Wilder uses Surmount at the labeled broadcast rate of 3 pints per acre. He also uses Sun-Pasture — not a good thing. Foliar herbicides enter surfactant at the rate of 1 quart per 100 the plant through the leaves, so you need gallons of spray mix. Surfactant helps the plenty of them to absorb the herbicide. solution spread out and stay on the leaves. So, maximize foliage, Wilder says, as His spray solution — herbicide, long as you can still get over the brush and surfactant and water — is usually 18.5 cover it with spray solution.

Fortnight = 14 days and nights. That’s how long Intrepid 2F insecticide controls ® armyworms, including fall armyworms, southern armyworms, beet armyworms and true armyworms — pests that can chew up a pasture overnight. Given the high value of intensively managed forage, it makes sense to protect it. Now, just in time for the 2008 season, Intrepid 2F is labeled for use in pastures and forage grasses grown for hay. “Armyworms are ferocious eaters, and they can come at you over a period of time,” says Ralph Lassiter, Dow AgroSciences product technology specialist. “So, having 14-plus days of residual control, as Intrepid 2F does, can save you repeat treatments compared with other insecticides.” Intrepid 2F also puts a halt on armyworm appetites quickly. Intrepid 2F has a novel mode of action that mimics the action of the molting hormone of armyworms. Upon ingestion of the insecticide, armyworms undergo an incomplete and lethal premature molt. This process stops their feeding. He has 3 rules for better brush control. John Wilder’s landlords depend on him advice for more than just lease payments. He defends their pastures from encroaching brush that would turn their tame grassland into the East Texas woods. He’s gotten pretty good at it, too. From the headquarters ranch he owns at Tyler, Texas, Wilder operates mostly on 3,000 leased acres scattered around the area. Those acres support a cow/calf herd and a significant hay business. In pastures, he continually fights blackberry, persimmon, locust and other woody species. “If we don’t do something, they’ll take over a place,” Wilder says. “Cows won’t go in these bushes. They stay away from that stuff. And there’s no grass under these big clumps of berry vines anyway.” To control that brush, Wilder — who does his Need another option for blackberry? own spraying — follows three cardinal rules of application that he shares Surmount® herbicide has become a popular option to control blackberry and other encroaching brush. But it’s not with his landowners and, the only option. now, you. PastureGard® herbicide also controls blackberry, either in a broadcast or hand-applied spray solution.

Because they have no soil activity, species Wilder fights tend PastureGard and Remedy Ultra also won’t interfere with clover germination in the fall.

The ratio of leaf surface to root mass goes down B lackberry is a tough competitor in many southern pastures, but it can be controlled. A determining factor, though, is when you spray. Don’t spray blackberry in the same year you’ve mowed, shredded or bush hogged it. You want the most foliage you can have and still get over it with a sprayer. With ample foliage, there are two good times of year to spray. The first is in the spring after leaves turn from light green to dark green. But the best time is after fruit drop, for as long as the leaves are healthy. Don’t spray during flowering, when the plants are putting on berries or the plants are drought-stressed. Drought stress often While feeding typically ceases within hours, complete mortality may take several days. “We call them walking dead worms,” Lassiter says. “You may still see them crawling, but they’re not doing any damage.” While highly effective against armyworms, Intrepid® 2F insecticide has no grazing restrictions for livestock and does not disrupt populations of most beneficial insects, including bees. Treatments with Intrepid 2F should begin at the first signs of feeding damage or when threshold levels of feeding damage occur. The labeled application rate is 4 to 8 fluid ounces per acre. The higher rate should be used for heavy infestations or advanced growth stages of targeted pests. Intrepid 2F is available in 1-gallon containers.

You have three good herbicide options: Surmount® herbicide; PastureGard® herbicide; or Remedy® Ultra herbicide tankmixed with GrazonNext™ herbicide. At recommended rates, all three have worked well. Don’t skimp on water in broadcast applications — 20, 30 or even 40 gallons of total volume is not too much. All the foliage should be wet with spray solution. Don’t mow dead-looking blackberry too soon after spraying. Allow the herbicide time to reach the roots. Wait a year. Spray blackberry at the right time. 7 Trademark of Dow AgroSciences LLC.
