Comparing Fitness Cost Associated with Haloxyfop-R Methyl Ester Resistance in Winter Wild Oat Biotypes [PDF]

Planta Daninha, 2020
: Consecutive application of herbicides has led to the evolution of herbicide-resistant weeds. This resistance is often associated with a fitness cost. Hence, a completely randomized design experiment with three replications was conducted to evaluate the

Regenerative Management and Phosphorus Fertiliser Effects on Dryland Pasture Yield and Botanical Composition in New Zealand

Grass and Forage Science, Volume 81, Issue 1, January-March 2026.
ABSTRACT This 3.5‐year grazed farmlet study investigated the impacts of regenerative agriculture and soil phosphorus (P) fertiliser on herbage dry matter (DM) yield and botanical composition in sheep‐grazed dryland pastures. Four treatments compared regenerative with conventional agriculture, under high and low P fertiliser, with Olsen P targets of 10 ...

Sustainable control of Dalbulus maidis: A field study with entomopathogenic fungi

Entomologia Experimentalis et Applicata, Volume 173, Issue 11, Page 1156-1164, November 2025.
Dalbulus maidis, a plant pathogen vector, poses a serious threat to maize production and food security. We investigated the potential synergistic effects between formulations based on entomopathogenic fungi and corn hybrids with varying resistance to maize stunt complex and Maize rayado fino virus. The combined management of M. anisopliae + B. bassiana

Development of cytosine and adenine base editors for maize precision breeding

Journal of Integrative Plant Biology, Volume 67, Issue 10, Page 2731-2743, October 2025.
A series of maize cytosine and adenine base editors was developed using various deaminase variants, enabling efficient multiplex genome editing in maize. Precise editing of the ZmACC1/2 genes generated herbicide‐tolerant maize germplasm, offering a solution for weed management in maize‐soybean intercropping systems.

Biology, Ecology, Distribution and Management of Large Crabgrass (Digitaria sanguinalis)

Weed Research, Volume 65, Issue 4, July/August 2025.
ABSTRACT Digitaria sanguinalis (L.) Scop. (large crabgrass) is a globally distributed annual C4 grass and one of the most challenging weeds in agriculture, causing significant yield losses in crops such as maize, soyabean, rice, cotton and vegetables. This species thrives under favourable and unfavourable conditions such as disturbed soils, fluctuating
