| Applications | Uses: Used as pre- or post-emergence herbicide for control of annual grasses and broad-leaved weeds in cotton, peanuts, vegetables, other crops, and forestry, [HSDB], Farming (Pesticides) [Category: Industry], For prometryn (USEPA, OPP Pesticide Code: 080805) ACTIVE products with label matches., SRP: Registered for use in the U.S. but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses., Substituted thiomethyl triazine herbicide, Herbicide, For most annual grasses, broadleaf weeds in cotton and celery. Applied to cotton broadcast or in band as preplant incorporated, preemergence., For more Uses (Complete) data for PROMETRYNE (9 total), please visit the HSDB record page., This is a man-made compound that is used as a pesticide., Use Classification: Pesticides -> Herbicides -> Triazine herbicides -> Methylthiotriazine herbicides, Methods of Manufacturing: Reaction of 2-chloro-4, 6-bis(isopropylamino)-s-triazine with sodium methyl mercaptide., ... Reacting propazine with methyl mercaptan in presence of 1 equiv of sodium hydroxide or by reacting 2-mercapto-4, 6-bis(isopropyl-amino)-s-triazine with methylating agent in presence of sodium hydroxide., Prometryn is produced by reaction of propazine with methylmercaptan in the presence of sodium hydroxide, followed by treatment with dimethyl sulfate., PREPARATION: H GYSIN, E KNUSLI, CH 337019, EIDEM, US 2909420 (BOTH 1959 TO GEIGY), Formulations, Preparations: CAPAROL 4L HERBICIDE Active Ingredient 44.4% Prometryn, COTTON-PRO Active Ingredient 45.41% Prometryn, GOWAN PROMETRYNE 4L Active Ingredient 44.4% Prometryn, PROMETRYN TECHNICAL Active Ingredient 97.0% Prometryn, For more Formulations, Preparations (Complete) data for PROMETRYNE (11 total), Consumption Patterns: Percent of Pesticide Applied to Crop: (1) Cotton, approximately 97 percent (1, 100, 000 - 1, 500, 000 lb active ingredient), of total domestic usage of prometryn, (2) celery, approximately 3 percent (31, 000-37, 000 lb active ingredient) of total domestic usage of prometryn, Percentage of Various U.S. Crops Treated with Prometryn, 1990-1992: Celery, 56-83%, 15-25 lb a.i., Cotton, 14-21%, 1, 100-1, 800 lb a.i., Other, 20-25 lb a.i., Prometryne: 1807X10+3, 1192X10+3, and 656X10+3 lbs ai, year in 1989, 1982, and 1976, respectively., U.S. Production: (1975) 9.53X10+6 G (CONSUMPTION), (1978) 9.53X10+6 G (CONSUMPTION), General Manufacturing Information: The WHO Recommended Classification of Pesticides by Hazard identifies Prometryne (technical grade) as unlikely to present an acute hazard in normal use, Main Use: herbicide., The 1992 Worker Protection Standard for Agricultural Pesticides (WPS) established certain worker-protection requirements (personal protective equipment, restricted entry intervals, etc.) to be specified on the label of all products that contain uses within the scope of the WPS. Uses within the scope of the WPS include all commercial (non-homeowner) and research uses on farms, forests, nurseries, and greenhouses to produce agricultural plants (including food, feed, and fiber plants, trees, turf grass, flowers, shrubs, ornamentals, and seedlings). Uses within scope include not only uses on plants, but also uses on the soil or planting medium the plants are (or will be) grown in. At this time all of the registered uses of prometryn are within the scope of the Worker Protection Standard (WPS). ... There are no registered products containing prometryn that are intended for homeowner use., Crop rotation restrictions or precautions usually are not required because of the shorter residual life & also because of the much greater safety margin which many sensitive plants have to methylthiotriazines compared to chloro or methoxytriazines., Applications may be made preemergence, post directed, and at layby in cotton. Preemergence applications in cotton can be incorp in AZ & CA. Postemergence applications are recommended for celery. Prometryn has considerable contact activity, therefore, postemergence treatments must be directed, exept in celery. Rates: 1.34 to 3.08 kg, ha (1.20-2.75 lb, acre) are usually required for selective preemergence of layby weed control, while rates of 0.54 to 0.72 kg, ha (0.48-0.64 lb, acre) are common for postdirected sprays to control emerged seedling weeds. Usual carrier: water at 187 to 374 L, ha (20 to 40 gpa) is the usual carrier for uniform application. Agitation in the spray tank is necessary to keep the chemical in suspension. ... Compatible with most other pesticides & fertilizers when used at normal rates. ... Glassware and spray equipment may be cleaned by washing with water, although prometryn should not be allowed to dry out or stand in sprayers., For more General Manufacturing Information (Complete) data for PROMETRYNE (8 total) |
