The implications of spatially variable pre-emergence herbicide efficacy for weed management. [PDF]
BACKGROUND The efficacy of pre-emergence herbicides within fields is spatially variable due to soil heterogeneity. We quantified the effect of soil organic matter on the efficacy of two pre-emergence herbicides; flufenacet and pendimethalin, against A.

Development of the novel pre-emergence herbicide pyroxasulfone. [PDF]
Pyroxasulfone, which was discovered and developed by K-I Chemical Research Institute Co., Ltd.; Kumiai Chemical Industry Co., Ltd.; and Ihara Chemical Industry Co., Ltd., is a novel pre-emergence herbicide for wheat, corn, and soybean. Pyroxasulfone inhibits the biosynthesis of very-long-chain fatty acids in plants and has shown excellent herbicidal ...

HELIOSEISMOLOGY OF PRE-EMERGING ACTIVE REGIONS. II. AVERAGE EMERGENCE PROPERTIES [PDF]
We report on average subsurface properties of pre-emerging active regions as compared to areas where no active region emergence was detected. Helioseismic holography is applied to samples of the two populations (pre-emergence and without emergence), each sample having over 100 members, which were selected to minimize systematic bias, as described in ...

Evaluation of pre-emergence herbicides in gladiolus (Gladiolus)
An experiment was carried out to evaluate the effect of different herbicides on weed control and growth and development of gladiolus (Gladiolus (Tourn) L.) cv.

Metabolic resistance to pre-emergence herbicides in grasses
Black-grass (Alopecurus myosuroides Huds.) and rye-grass (Lolium spp) are very competitive grass weeds. During the last decades, they have evolved resistance to post-emergence herbicides, in particular ACCase- and ALS- inhibitors.

Herbicide selectivity and weed control in gladiolus cultivation [PDF]
The objective of this work was to evaluate the selectivity of pre- and post-emergent herbicides and their efficiency in weed control, as well as the growth and quality of floral stems, in a gladiolus (Gladiolus x grandiflorus) crop in two growing seasons.

Controlling watergrass in corn: With pre-emergence herbicides
Four years of testing have shown that chemicals incorporated in the soil as pre-emergence treatments give satisfactory control of watergrass and many broad-leaved weeds in corn growing in the organic soils of the Sacramento-San Joaquin Delta.

Pre-emergence herbicides for weed control in lettuce
California lettuce growers spend $11,620,000 per year for weed control. Although mechanical cultivation will control weeds in the furrow and between rows, weeds in the seed row are still controlled by hand chopping at approximately $20 to $60 per acre ...

Tolerance of cowpea cultivars to pre-emergence application of sulfentrazone
Improved methods of weed control are required to support expansion of large-scale cowpea cultivation in mid-west Brazil. With the aim of testing our hypothesis that the tolerance of cowpea cultivars to sulfentrazone is dose- and genotype-dependent, we ...

Residual herbicides increase the period prior to interference in soybean cultivars [PDF]
Background: The pre-emergence herbicides diclosulam and flumioxazin are used to weed control in soybean. We hypothesized management of the new emergence of weeds in the early development stages of the soybean could alter the periods of interference ...
