Pacific Northwest Forest and Range Experiment Station. Timberland herbicide spraying sickens a community robbing fast-growing Douglas-fir seedlings, the industry’s big moneymaker, of sunlight.

Atrazine and 2,4-D, two of the most commonly. Killing any tree seems a shame, but pine trees can become diseased, overgrown or may be situated in an inconvenient area. Killing a mature pine tree can be difficult. Forest management professionals sometimes resort to burns, banding and chemical treatments and yet often the trees still come back.

For example, both 2,4-D esters and EPTC vaporize rapidly and may affect nontarget plants in the near vicinity. The use of 2,4-D near certain crops has been restricted in some states (e.g., California and Texas) to prevent damage to highly sensitive crops.

Most of the herbi- cides mentioned in Table 1 are more soluble in water than are insecticides. To gain a better understanding of how sublethal rates of dicamba and 2,4-D influence sugarbeet, studies were conducted in East Lansing and Richville, MI.

Five rates ranging from % of the field use rates of dicamba and 2,4-D were sprayed on sugarbeet at the 2-leaf, 6-leaf, and leaf growth stages. Full text of "Pesticides documentation bulletin" See other formats.

PRODUCTION INFORMATION Gramoxone SL is a contact Group 22 herbicide used to control or suppress a broad spectrum of emerged weeds.

It controls most small annual weeds –. PRODUCT INFORMATION Tavium Plus VaporGrip Technology is a foliar systemic broadleaf herbicide with residual control of grass and certain broadleaf weeds in: dicamba-tolerant cot.

Compositions and methods comprising polynucleotides and polypeptides having dicamba decarboxylase activity are provided.

Further provided are nucleic acid constructs, host cells, plants, plant cells, explants, seeds and grain having the dicamba decarboxylase sequences.

Various methods of employing the dicamba decarboxylase sequences are provided. Compositions and methods comprising polynucleotides and polypeptides having dicamba decarboxylase activity are provided. Further. Compositions and methods comprising polynucleotides and polypeptides having 4-hydroxyphenylpyruvate dioxygenase (HPPD) activity and having insensitivity to.

The addition of metsulfuron to the mixture of aminocyclopyrachlor plus 2,4-D was more effective in the control of kudzu than that observed by aminocyclopyrachlor plus 2,4-D. In the greenhouse, aminocyclopyrachlor applied at 66 g ai/ha plus 2,4-D at g ai/ha provided 53% visual control and 63% biomass reduction of Chinese privet.

2,4-D acid and auxin cataholism in barley and wheat was examined by Fooz, et_ al_., (). Cffccb of 2,4-D on growth and IAA catabolism (in vitro and vivo) in the dark showed increasing concentrations of 2,4-D inhibited germination and growth.

2,4-D metabolism in resistant grasses was studied by Hagin, et al., (). A mixture of 2,4-D with other herbicides can be used effectively on cool-season grass seedlings of such species as Kentucky bluegrass, red fescue, and tall fescue if applied at 1/4 to 1/3 the rate used in established turf (attachment 11).
