The Pesticide Notification Network is operated by the Washington State
University Pesticide Information Center for the Washington State Commission
on Pesticide Registration. The PNN system is designed to distribute pesticide
registration and label change information to groups representing Washington's
pesticide users. The information below is a summary of the information distributed
on the PNN in the past month.
Our office operates a web page called PICOL (Pesticide Information Center On-Line). This provides a label database, status on registrations, and other related information. PICOL can be accessed on URL http://picol.cahe.wsu.edu or call our office, (509) 372-7492, for more information.
Novartis has revised the label for its fungicide Orbit. The new label includes directions for use on apricots, cherries, nectarines, peaches, plums, and prunes for growing areas west of the Rocky Mountains.
Manufacturers' Product Cancellations
In the February 11, 1998, Federal Register, the Environmental Protection Agency announced that it had received a request from Platte Chemical to cancel the registration for its herbicide Trifluralin 4EC. This product is currently registered for use on: alfalfa, apricot, asparagus, broccoli, Brussels sprouts, cabbage, carrot, cauliflower, celery, collard, dry bean, field corn, grape, green bean, hop, kale, lima bean, mint, mung bean, mustard, nectarine, non-bearing apricot, non-bearing grape, non-bearing nectarine, non-bearing peach, non-bearing plum, non-bearing prune, non-bearing walnut, okra, pea, peach, pepper, plum, potato, prune, safflower, sorghum, soybean, sugarbeet, sunflower, tomato, turnip, walnut, and wheat.
Section 18 Crisis Exemptions
EPA has denied the Section 18 request that was submitted at the end of January for the use of Comply to control pear psylla on pears. Because Section 18's have been granted for the use on Comply on pears in previous years (1994 through 1997), the Washington State Department of Agriculture is warning growers that using Comply on pears in 1998 is NOT legal, and could lead to enforcement action against the applicator. WSDA is revising the Section 18 request and will substitute an alternative product for Comply. Questions should be directed to Erik Johansen (WSDA). He can be reached on (360) 902-2078 or by E-mail at firstname.lastname@example.org.
On February 25, 1998, WSDA issued a Section 18 crisis exemption for the use of Ciba-Geigy's herbicide Beacon to control weeds in Kentucky bluegrass seed. This exemption expires November 30, 1998.
Section 18 Specific Exemptions
On January 29, 1998, the EPA granted a specific exemption for the use of Prowl 3.3EC to control kochia and redroot pigweed on mint. The exemption is for use on 9,800 acres in Adams, Benton, Clark, Ferry, Franklin, Grant, Kittitas, Lincoln, and Yakima counties and expires 12/31/98.
Du Pont has issued a supplemental label for its herbicide Lexone DF. The supplemental label provides for the use of this product to control weeds in established tomatoes.

On February 4, 1998, WSDA issued an SLN, number WA970037, for the use of Platte Chemical's herbicide Trifluralin HF on evening primrose seed grown for export to the United Kingdom.

Section 24(c) Cancellations

At Platte's request, WSDA has cancelled SLN WA910007. This SLN was previously issued for the use of Tenax to control aphids, leafhoppers, leaf miners, psyllids, flea beetle larvae, wireworms, and the reduction of flea beetle adults and early season Colorado potato beetles in white Irish potatoes.
At Platte's request, WSDA has cancelled SLN WA930010. This SLN was previously issued for the use of Rampart 10 to control aphids on hops.

On January 27, 1998, WSDA issued a revision to SLN WA96003. This SLN had previously been issued for the use of Dimethoate 4E to control aphids and grasshoppers in phragmites reed beds in Grant county. (These reed beds constitute a portion of the wastewater treatment at a potato processing plant near Quincy, Washington) The following sections of the registration have been revised: the distribution and use statement, the precaution statement, the Federal law violation statement, the addition of a chemigation statement, the scientific name, and the section covering Worker Protection Standards.
