Japanese bindweed was found to be one of the most abundant and most difficult-to-control weed species during a 2-yr weed survey in more than 100 winter wheat fields in the North China Plain region. Multivariate data analysis showed that Japanese bindweed is most abundant at sites with comparative low nitrogen (N) fertilization intensities and low crop densities. To gain deeper insights into the biology of Japanese bindweed under various N fertilization intensities, winter wheat seeding rates, herbicide treatments, and their interactions, a 2-yr field experiment was performed. In nonfertilized plots, a herbicide efficacy (based on density reduction) of 22% for 2,4-D, and of 25% for tribenuron-methyl was found. The maximum herbicide efficacy in Nmin-fertilized plots (target N value based on expected crop yield minus soil mineral nitrogen content,) was 32% for 2,4-D and 34% for tribenuron-methyl. In plots fertilized according to the farmer's practices, a maximum herbicide efficacy of 72% for 2,4-D and of 64% for tribenuron-methyl could be observed. Furthermore, medium and high seeding rates improved the herbicide efficacy by at least 39% for tribenuron-methyl and 44% for 2,4-D compared to the low seeding rate. Winter wheat yield was not significantly affected by seeding rate itself, whereas at low and medium seeding rates, Nminfertilization was decreasing winter wheat yield significantly compared to the farmer's usual fertilization practice. At the highest seeding rate, Nminfertilization resulted in equal yields compared to the farmer's practices of fertilization.

Since the inception of 2,4‐D [(2,4‐dichlorophenoxy) acetic acid], many herbicides have been developed for broadleaf weed control in wheat (Triticum aestivum L.). However, many of these herbicides have not been thoroughly evaluated with respect to application timing and effects on wheat yield and quality. Field studies were conducted at Torrington, WY on a Bayard fine sandy loam (coarse loamy, mixed, mesic Torriothentic Haplustoll) in 1984 and 1985 to evaluate the response of ‘Oslo’ spring wheat to 10 broadleaf herbicide treatments applied at three growth stages. Dicamba (3,6‐dichloro‐2‐methoxybenzoic acid), dicamba plus 2,4‐D and dicamba plus MCPA [(4‐chloro‐2‐methylphenoxy)acetic acid] reduced wheat yield 28, 21 and 24%, reduced kernels per spike 27, 33 and 21%, and increased seed protein 8, 10 and 13%, respectively, when applied at Zadoks Stage 44 (mid‐boot). Several other auxin herbicides increased seed protein content, particularly when applied at Zadoks Stage 44. Proline and lysine content were not influenced by herbicide treatment at any stage of application. Spring wheat tolerance to bromoxynil (3,5‐dibromo‐4‐hydroxybenzonitrile), chlorsulfuron (2‐chloro‐Ar‐[[4‐methoxy‐6‐methyl‐l,3,5‐triazin‐2‐yl)amino]carbonyl] benzenesulfonamide} and MCPA was excellent regardless of growth stage at application.

“…In Lebanon some work has been conducted on the tolerance of wheat and barley a t different stages of growth to 2,4-D sprays (Saghir and Aqiqullah, 1970) and on the amino acid composition of the grain protein of wheat and barley treated with this herbicide (Pellett and Saghir, 1971). About 5% of the pesticides imported by Lebanon are herbicides, with 2.4-D being the principal chemical used on cereals.…”
