1. Potato production in the United States in was estimated at ,, cwt from 1,, acres. 2. Results of a comprehensive survey placed cost of weed control at $ per acre, plus increased production and harvest costs of $ per acre. In addition, there was an average loss of cwt per acre in yield assigned to lack of weed control. Total loss to the industry was Cited by: This paper reviews different programs and strategies of haulm destruction that incorporates a new active ingredient: the pyraflufen-ethyl. Applied 5 days after a desiccant as glufosinate ammonium or diquat, it presents on leaves and stems similar efficacy to the carfentrazone ethyl used under the same conditions. The use of a flail to remove potato foliage followed by the application of Author: C. Vacher. Weed cover: If annual meadow grass, chickweed, couch or any other weed which will continually grow throughout the autumn are present then burning will give best control and reduce harvesting difficulties. Any reduction in weed cover will reduce cover for slugs. Timing: Ideally haulm destruction should be carried out when the potatoes have reached. Haulm Destruction Method on the Development of Disease in Seed Tuber Production. Ref: R desiccation using desiccants may achieve haulm destruction more effectively. Since the withdrawal of sulphuric acid as an option for haulm destruction, seed potato growers have had to convert to other methods of haulm Size: 1MB.
R Haulm Destruction in Seed Crops. Aim: To identify the impact of haulm destruction method on disease risks in seed potato production, and follows up on project R Industry Challenge Since the withdrawal of sulphuric acid as an R Haulm Destruction and Blackleg. Control of virus diseases Insect control 14 Carves* Haulm destruction Methods of haulm destruction Stem end and vascular ring necrosis Harvesting operations, transport and storage Time between lifting and collection ! Studies were carried out during at 2 sites in the Netherlands to determine the optimum period for haulm destruction (based on the use of solar radiation for tuber production) in 5 potato cultivars (Seresta, Karnico, Elles, Florijn and Kartel). Crop yield, ground cover and solar radiation were monitored during July-October. Ground cover was measured using 3 different methods (visual Author: K. H. Wijnholds, C. D. van Loon. A Review of Non-Chemical Weed Control Techniques. S. Parish. The West of Scotland College, Auchincruive, Ayr, KA6 5HW, Scotland* Other applications of flaming are for onion and potato haulm destruction. The author would like to thank Nic Lampkin for the opportunity to read the manuscript of the Weed Management chapter of his book.
Find out which are the most efficient herbicides and application methods for weed control management in potatoes. Late Blight. Late blight remains the single most important potato disease, costing the industry an estimated £50M annually in crop protection chemicals in a typical blight pressure season. In two-years examination of efficacy of chemical weed control in potato cr op in the vicinity of Kolašin 24 weed sp ecies were recorde d (23 in and 18 in ). FORMULATED FOR WEED CONTROL IN POTATOES • Outstanding broad-spectrum pre- and post-emergent control of many weeds • Formulated to deliver excellent results and labeled for use on a wide range of crops, including potatoes • Long-lasting residual control COMPETITIVE ADVANTAGES Keep weeds under control with new Grapple™ Herbicide. The unweeded control yielded the least marketable potatoes of all treatments (table 1) and produced 61% less than the weed-free control. The greatest potato tuber yields were noted in plots treated with metribuzin alone or in combination with metolachlor or pendimethalin.
