SELECTIVITY OF METRIBUZIN IN POSTEMERGENCE OF CULTURE OF CARROT [PDF]
Planta Daninha, 2017 The initial slow growth and short stature of carrot can allow that weeds settle in crop areas, requiring the management of these plants for productivity not to decrease.

Proceedings of the Integrated Crop Management Conference, 2006 Postemergence herbicides are the most widely used weed management tool in Iowa's corn and soybean acres. Application of the herbicide directly to the target bypasses the myriad of soil interactions that influence preemergence herbicides. However, killing

Factors Affecting Postemergence Herbicide Activity
Proceedings of the Integrated Crop Management Conference, 1992 Postemergence herbicides have become an increasingly important tool in weed management systems. Reasons for this increase include the introduction of new products, environmental concerns, and changes in production practices. Several factors influence the

Postemergence herbicides and application time affect wheat yields
California Agriculture, 1996 Experiments conducted on wheat grown in the Sacramento and San Joaquin valleys found that two of the most critical factors in reducing plant injury are choice of postemergence herbicide and the growth stage at which the herbicide is applied.

Italian Journal of Agronomy, 2021 For optimum postemergence crabgrass (Digitaria spp.) control, a single quinclorac herbicide application could be properly timed and delivered with spray nozzles that produce spray droplets ranging from very coarse (401 - 500 µm) to medium (226 - 325 µm ...

Mesotrione Applications for Postemergence Crabgrass Control
, 2006 The objective of this research was to determine the following: 1) what rates of mesotrione provide acceptable (> 80%) weed control, 2) if these rates are nonphytotoxic to turfgrasses, 3) if the addition of prodiamine is beneficial at late postemergence timings, and 4) if the residual activity is acceptable.

2008 Postemergence Crabgrass Efficacy Trial
, 2009 The objectives of this study were to compare the efficacy of Drive XLR8 to Drive 75DF and to compare Drive XLR8 to several other postemergence crabgrass products at two different crabgrass growth stages.

Protecting Crop Yields with Postemergence Herbicides
Proceedings of the Integrated Crop Management Conference, 2004 Postemergence herbicides are an important component of today's weed management systems. Herbicides introduced in the past 10 years for use in both corn and soybeans are able to kill much larger weeds than earlier products, thus providing farmers with ...

Can species adapt to drought using multiple strategies? Lessons from the California poppy. [PDF]
New PhytolSummary Plants can escape drought by completing life cycles early, tolerate drought by increasing physiological limits, or avoid drought stress by obtaining or using water more efficiently. It remains unclear whether strategies vary within species across their distributional ranges due to trade‐offs, and whether species can exhibit plasticity in ...
