Autumn Strawberry Update: the chances of botrytis and rots developing on the fruits have increased due to weather
Soft Fruit Agronomist, Dr Neil Holmes, gives an autumn strawberry update. As strawberry crops approach the autumn season, several challenges remain for late 60-day June bearer and ever bearer crops. Inclement weather over recent weeks has increased the chances of botrytis and rots developing on the fruits. By the time grey mould has developed on the fruit, there is little that can be done to ...

European Court Annuls Prior Judgments to Protect Testing Information Related to Glyphosate Authorization
On March 7, 2019, in the Court of Justice of the European Union (EU), the Eighth Chamber of the General Court issued two judgments in cases regarding access of confidential information related to glyphosate. One of these decisions (Tweedale v. EFSA, Case T-716/14) related to a 2014 request for two toxicity studies that were “key studies” in the determination of glyphosate’s ...

How to make optimal condition for growing vegetables
The competition between vegetable producers, high production costs, expensive seeds and many other factors, mean that vegetable producers want to provide optimal conditions for their cropping. They want to get the best product that will meet the high customer’s needs. In addition to investing in seeds, fertilizers and plant protection products, you need the suitable equipment. This will ...

Re‐calibration of the earthworm tier 1 risk assessment of plant protection products
In the first step of the earthworm risk assessment for plant protection products the risk is assessed by comparing the no‐observed effect levels (NOEL) from the laboratory reproduction tests with the predicted exposure of the plant protection product in soil while applying a trigger value (assessment factor; AF) to cover uncertainties. If this indicates a potential risk, field studies are ...

Population‐level effects and recovery of aquatic invertebrates after multiple applications of an insecticide
Standard risk assessment of plant protection products (PPP) combines ‘worst‐case’ exposure scenarios with effect thresholds using assessment (safety) factors to account for uncertainties. If needed, risks can be addressed applying more realistic conditions at higher tiers, which refine exposure and/or effect assessments using additional data. However, it is not possible to investigate the wide ...

European Court of Justice Dismisses Case Regarding Confidential Treatment of Information Submitted to EFSA
On June 3, 2015, the General Court of the European Court of Justice issued a ruling in Luxembourg Pamol (Cyprus) Ltd. and Luxembourg Industries Ltd. (Luxembourg) vs. European Commission regarding the publication of information by the European Food Safety Authority (EFSA) in its peer reviewed draft assessment report of potassium phosphonate that Luxembourg claimed as confidential. The case was ...

An evaluation of fish early life stage tests for predicting reproductive and longer term toxicity from plant protection product active substances
The chronic toxicity of chemicals to fish is routinely assessed by using fish early life stage (ELS) test results. Fish full lifecycle (FLC) tests are generally only required when toxicity, bioaccumulation, and persistence triggers are met, or when there is a suspicion of potential endocrine disrupting properties. This regulatory approach is based on a relationship between the results of fish ...

Saving two birds with one stone — using active substance avian acute toxicity data to predict formulated plant protection product toxicity
Environmental safety assessments for exposure of birds require the provision of acute avian toxicity data on both the pesticidal active substance and formulated products. As an example, in Europe testing on the formulated product is waived using an assessment of data for the constituent active substance(s). Globally this is often not the case as some countries require acute toxicity tests with ...

Evaluating exposure and potential effects on honeybee brood (Apis mellifera) development using glyphosate as an example
This study aimed to develop an approach to evaluate potential effects of plant protection products on honeybee brood with colonies at realistic worst‐case exposure rates. The approach comprised two stages. In the first stage, honeybee colonies were exposed to a commercial formulation of glyphosate applied to flowering Phacelia tanacetifolia with glyphosate residues quantified in relevant ...

Possibilities for Future EC Environmental Policy on Plant Protection Products
Abstract This report presents the results of a study to examine and evaluate the economic, environmental and social benefits of plant protection products (PPPs) in agriculture with the main emphasis on the economic aspects. The approach followed was to carry out four case studies - each covering a single crop in a specific region of major production-comparing standard, integrated and organic ...

Regional Analysis of use Patterns of Plant Protection Products in Six EU Countries
Abstract This study followed a review conducted by LEI-DLO in Phase 1 of the project on possibilities for future EU environmental policy on plant protection products (PES-A). In their review LEO-DLO suggested three avenues for investigation: Areas of more than moderate use of plant protection products: Germany - Nordrhein Westfallen, Rheinland Pfalz, Berlin France - Champagne-Ardennes, ...
