• BASF Kixor Herbicide Receives EPA Approval

EPA has registered a new active ingredient, BASF’s Kixor (saflufenacil) herbicide, for use on a wide range of crops and effective on more than 70 broadleaf weeds.

Kixor’s chemistry inhibits a key step in chlorophyll biosynthesis, resulting in fast control of broadleaf weeds.

Treevix herbicide, powered by Kixor, is designed for directed, postemergence applications in bearing and nonbearing tree crops (citrus fruit, pome fruit, and nuts). It is a tree-safe, non-volatile herbicide.

BASF’s OpTill herbicide uses Kixor technology for burndown and residual weed control in chickpeas and dry field peas when applied preplant through preemergence.

• Pruvin Herbicide From MANA

MANA Crop Protection introduces Pruvin rimsulfuron herbicide for control of some of the toughest broadleaf and grass challenges to vegetables, fruit, tree, nut and vine crops, field corn, and non-crop areas.

Pruvin is quickly absorbed through roots and foliage of selective weeds, rapidly inhibiting growth. The residual control helps save the time and expense of additional passes across the field.

Pruvin can be applied to tomatoes and potatoes in preemergence, postemergence, or split applications. According to Dave Downing, senior marketing manager for MANA herbicides, Pruvin is not a restricted-use product. The preharvest intervals are a three to 14 days, depending on the crop.
In addition, Downing says the herbicide “can be used alone or in combination with other labeled soil residual and burndown products, which can extend the residual activity, broaden the weed spectrum targeted, and improve control of susceptible weeds.”

Pruvin is a good choice for weed control in established permanent crops such as grapes, stone fruit, tree nuts, apples, and citrus.

• Burndown Herbicide From Marrone Organic Innovations Gets The Nod In California

GreenMatch (d-limonene or extract of citrus) burndown herbicide is now available in California for use in organic crops. From Marrone Organic Innovations, GreenMatch meets the requirements of the National Organic Program for use in organic agriculture and is listed by the Organic Materials Review Institute and the Washington State Department of Agriculture. It has a full EPA registration for crop and non-crop application.

GreenMatch is a post-emergence, non-selective organic herbicide that contains extract of citrus as well as other plant extracts and surfactants. GreenMatch kills the weeds by stripping the wax off the leaves of the plants, causing weeds to rapidly shrivel and die, appearing “burned down.”

It is said to be fast-acting, easy to apply, and active on a broad spectrum of weeds. This new tool provides organic growers with a viable alternative to costly hand weeding, flame weeding, mowing and cultivating in their battle to control weeds, according to the company. GreenMatch is non-selective, and controls most annual and perennial weeds, both grasses and broadleaves.
