Confirmation of glyphosate-resistant waterhemp (Amaranthus tuberculatus) in New York
Weed TechnologyWaterhemp has become a serious management challenge for field crop growers in New York. Two putative glyphosate-resistant (GR) waterhemp populations (NY1 and NY2) were collected in 2023 from two soybean fields in Seneca County, NY. The objectives of this

Influence of soybean row spacing and postemergence herbicide timing on control of foxtail species (Setaria spp.) [PDF]
, 1996 The elimination of cultivation by narrow row, no-till programs has changed weed control programs, with postemergence herbicides playing a larger role. Many of the postemergence herbicide products available provide better control of larger weeds than what

Influence of saflufenacil encapsulation on corn phytotoxicity and residual broadleaf weed control
Weed TechnologySaflufenacil, a herbicide that inhibits protoporphyrinogen oxidase, has been reformulated as a microencapsulation for preemergence and postemergence applications to corn, with the primary purpose of the encapsulation to reduce the risk of corn injury ...

Postemergence Herbicide Weed Control in Onions
, 1996 Onions treated at the 2-leaf stage of growth with the 3rd leaf just beginning to emerge with postemergence herbicides bromoxynil (Buctril®) and oxyfluorfen (Goal®) exhibited slight injury at 11 days after treatment (DAT) but had recovered to show no ...

Postemergence herbicides in Swedish willow stands
Bioresource Technology, 1988Abstract Eleven herbicides were tested for postemergence use in newly established stands of Salix viminalis and Salix dasyclados. Spraying was carried out at two rates and at two stages of growth (shoot lengths 5–7 cm and about 15 cm respectively). Effects on Salix plants were estimated by regular observations of damage symptoms during the growing ...

Postemergence Activity of Isoxaben
Weed Technology, 1994Barnyardgrass and many broadleaf weeds were severely stunted by POST applications of isoxaben. Most grasses were only moderately affected by isoxaben at rates up to 1 kg/ha. POST activity was enhanced by soil interception, but evident with foliar interception alone.

Postemergence Herbicides for Calendula
Weed Technology, 2012Calendula is an alternative oilseed crop whose seed oil is valued as a substitute for tung oil and a replacement for petroleum-based volatile organic compounds in paints and other coatings. Calendula tolerances to most POST-applied herbicides are unknown. Two POST-applied herbicides were tested for tolerance by calendula.
