WRAG response on Trifluralin (3 pages pdf) At its May (2007) meeting the Weed Resistance Action Group (WRAG) steering committee discussed the implications of the loss of trifluralin, which has not been included in Annex 1 of Directive 91/414 and will be withdrawn by the middle of 2009.
Ten facts everyone should know about herbicide resistance Ten facts everyone should know about herbicide resistance. HRAC Website > Home. Section 2: Describing the growth of your crop as stages. During which stages is yield determined? The Zadoks decimal growth stages Growth is a complex process with different organs developing, growing and dying in overlapping sequences.
However, it is easier to think of it as a series of growth stages as in the Zadoks scale. This has 10 main stages, labelled 0 to 9, which describe the crop. These are named in the following table. Table of the Zadoks decimal growth stages (Z0.0 to Z9.9) MS = main shoot or parent shootGrowth stages follow Zadoks, J.C., Chang, T.T., Konzak, C.F. (1974) Decide first which of the main stages best describes your crop. Main stages 1 and 2 describe leaf and tiller production that actually occur in parallel, not in sequence. HM Rawson. Cereal Disease Encyclopedia - Rhynchosporium (Leaf Scald) Pathogen Rhynchosporium secalis Hosts The disease affects barley, rye, triticale and a number of grasses, particularly ryegrasses.

For purposes of trade, registration and legislation, and for use in popular and scientific publications, pesticides need names that are short, distinctive, non-proprietary and widely-accepted. Systematic chemical names are rarely short and are not convenient for general use, and so standards bodies assign common names to the active ingredients of pesticides. More than 1200 of these official common names for pesticides have been assigned by the International Organization for Standardization (ISO). This Compendium is believed to be the only place where all of the ISO-approved standard names of chemical pesticides are listed. The Compendium contains much more than ISO common names, with nomenclature data sheets for more than 1700 different active ingredients and for more than 350 ester and salt derivatives, made accessible by a comprehensive set of indexes and a classification.

USDA MRL DATABASE: Disclaimer. Plant Production and Protection Division: The Joint FAO/WHO Meeting on Pesticide Residues (JMPR) The Joint FAO/WHO Meeting on Pesticide Residues (JMPR) The "Joint Meeting on Pesticide Residues" (JMPR) is an expert ad hoc body administered jointly by FAO and WHO in the purpose of harmonizing the requirement and the risk assessment on the pesticide residues The JMPR has met annually since 1963 to conduct scientific evaluations of pesticide residues in food.
It provides advice on the acceptable levels of pesticide residues in food moving in international trade. The JMPR consists of experts who attend as independent internationally-recognized specialists who act in a personal capacity and not as representatives of national governments. The current JMPR comprises the WHO Core Assessment Group and the FAO Panel of Experts on Pesticide Residues in Food and the Environment. The FAO Panel is responsible for reviewing pesticide data residue and for estimating maximum residue levels, supervised trials median residue values (STMRs) and highest residues (HRs) in food and feed.
