One of the most important factors in mechanical control of weeds is the management of soil cultivation practices. Mechanical pest control in agriculture is the use of hands-on techniques as well as simple equipment and devices, that provides a protective barrier between plants and insects. Therefore, any factors affecting produce must be acted on swiftly and in a cost-effective way. In tropical zone, the most widespread control method against weeds remains manual weeding. Tillage can help minimize damage from soil-dwelling insects by directly killing the insect, exposing insects to predation by birds or other predators, and by helping the plant grow more rapidly (this . Technically simple, this operation must however respect several constraints : The critical period of harmfulness is generally situated. Testing harrows for mechanical control of annual weeds in agricultural crops. Mechanical Pest Control This is an old method of controlling the pest. between 15 and 60 days after sowing for short cycle annual crops (cotton, maize, sorghum, etc.). Increasing air passenger traffic and demand for commercial aircraft are likely to drive market growth in the coming years. manual weeding needs between 10 and 20 days of work per hectare, following the standards obtained in dryland row crops ; manual weeding is a very tedious activity ; family or hired labour, workers are not always available ; when crops have been established, over usually a period of one month, there is a competition in the preparation of the work calendar between the crops to be sowed last and the weeding to be done in those first sowed. Monitor and control your irrigation system with a mobile app. Smith (ed.). Rotary hoeing is effective on weeds that have germinated but not yet emerged but not on weeds that germinate from deeper than 5 cm, on no-till fields, or on fields with more than 20 to 30 percent crop residue. It is literarily getting rid of the pest by killing them or creating barriers that prevent them from attacking the agricultural produce. Mulching is successful with most annual weeds, however, some perennial weeds are not affected Mulches may be organic or synthetic. Ascard J., (1995). Mechanical pest control methods involve. For crops with wide inter-rows (cotton, maize, sorghum, millet, manioc, sugar cane, etc), mechanical weeding has the following advantages : However, the practice of mechanical weeding implies some constraints : For mechanised farms, chopping is a current technique for the maintenance of plots, Return to the page "Weed science : everything about weeds". The C/M Section uses chemical (pesticides) and/or mechanical (rouging, trapping, modifying habitats) approaches to eliminate or mitigate pest problems. Matrise des adventices par voie non chimique; errata et complment, Thme 3, Comm. Mechanical controls range from small cutting boats to 90-foot long harvesters, and from shredders that slurry plants to track hoes and draglines stationed on shorelines or mounted on barges that lift plants and debris out of the water. J. Advantages of Mechanical Methods of IPM (Integrated Pest Management) 1. One of the most common methods is replacing susceptible plants and new irrigation methods (e.g., reducing irrigation can deprive weeds of sufficient moisture and promote root health).. The 5 general categories of weed control are: Preventative Weed Control Cultural Weed Control Mechanical Weed Control Biological Weed Control Chemical Weed Control Definitions Depending on the type of pests, we can distinguish several different pest control methods which include biological pest control, mechanical pest control, However, these methods cause minimum damage to the environment. Therefore, the effectiveness of this method is dependent on the removal of as much of the root system as possible. Mechanical, physical and cultural control of pests, weeds and diseases (pests) are an integral part of a successful Integrated Pest Management plan. Skilled labours are not required. gardener may resort to pesticides to control a pest invasion, but there are also many non-chemical alternatives. in pasture lands, to cut harmful species. 3. Some examples of physical and mechanical pest controls include: tillage.
