Banana leaf and glucose mineralization and soil organic matter in microhabitats of banana plantations under long‐term pesticide use
Soil organic matter (SOM) and microbial activity are key components of soil quality and sustainability. In tropical humid tropics of Costa Rica three pesticide regimes were studied: fungicide (low input); fungicide and herbicide (medium input); and fungicide, herbicide and nematicide (high input), under continuous banana cultivation for 5 (young) or 20 (old) years, in three microhabitats: ...

The relative sensitivity of macrophyte and algal species to herbicides and fungicides: An analysis using species sensitivity distributions
Lemna spp. are the standard test species representing aquatic macrophytes in the current risk assessment schemes for herbicides and plant growth regulators in the European Union and North America. At a Society of Environmental Toxicology and Chemistry (SETAC) workshop on Aquatic Macrophyte Risk Assessment for Pesticides (AMRAP), a Species Sensitivity Distribution (SSD) working group was formed ...

Pesticides in urban streams and early life stages of pacific coho salmon
Pesticides are frequently detected in urban streams and are believed to be primarily the result of homeowner use. Although concentrations in most cases are low (<1 µg/L), there is concern that pesticide inputs threaten efforts to restore and enhance salmon habitat. The authors exposed early life stages of coho salmon (Oncorhynchus kisutch) to a pesticide mixture (“cocktail”) representative of ...

Strict environmental regulations require the company to capture and neutralize all surface runoff and grey water produced at the plant before disposing into the municipal system. In addition, air permits prohibit any odors to cross their fence lines. As the water collects ...

Tips for a successful crop scouting
You will often hear the statement “the best thing to put into your field is your shadow” or your “footprint”, or “boots” and the list goes on. This statement is very true, but begs the question “how can I be more effective when I am in my fields?” Understanding where to look first, what to look for or knowing where to look based on ...

Pesticide runoff from greenhouse production
A research has been undertaken studying pesticide residues in water from greenhouses and the use of soils and filter materials to reduce such losses. The pesticides detected in water samples collected downstream greenhouses include 9 fungicides, 5 herbicides and 4 insecticides. 10 compounds from flower and vegetable productions were frequently found to exceed environmental risk levels, and with a ...

Pesticides in the European Union
There has been a sharply falling trend in the total volume of sales of agricultural pesticides in the EU between 1991 and 1995. But this was reversed in 1996. From 1991-1995, EU sales of pesticides, measured by weight of active ingredients (ai), fell by 13%. They then rose by 6% between 1995 and 1996 to stand at 299,826 tonnes ai. But this still put them nearly 8% below the 1991 figure. The use ...

Crop rotation and soil health
They go together like salt and pepper – they’re better together When you have a strong and varied crop rotation, it produces a greater diversity in the soil microbiome, which improves activity both above and below the surface. One of the most critical parts about a healthy crop rotation is bacteria – both good and bad – because when you change crops, you change pathogens. ...
