By Francesca Camillo From the May issue of Acres U.S.A. magazine. Flame weeding (also referred to as flaming) has been an apt option for organically ridding row crops and fields of uninvited weeds while also replenishing the soil with nutrients from the resulting carbon.
Wedding the proficiency of flame with the compressed liquid power of propane has served many farmers and food. The SpHot Weeder™ enables treatment precision that has never been available before, making flaming weeds more controllable with greater impact at less cost; These benefits are achieved by capturing, containing, focusing, and directing the thermal energy produced by an open flame torch.
This book deals with the principles, concepts, technology, potential, limitations and impacts of various non-chemical weed management options. It contains 12 chapters discussing topics on prevention strategies in weed management, exploitation of weed crop interactions to manage weed problems, cultural methods, cover crops, allelopathy.

Flaming is now one of the most widely used methods of thermal weed control (Cisneros and Zandstra, ), particularly in organic agriculture. Other practices such as stale seedbed technique also include preemergence flaming for weed control. Flame weeding has several advantages compared to other methods of weed control.
There was a highly positive correlation between the temperature sum and control of S. alba by flaming and infrared radiation based on temperatures measured at the upper position.
It is concluded that evaluating thermal weeders based solely on indiscriminate temperature measurements is unreliable: proper comparison has to take into account the.
One of the non-chemical alternatives for weed control is the use of propane weed flaming, i.e., flaming.
This method has become the major thermal weed control tactic in organic cropping systems in the US, such as soybean (Glycine max), corn (Zea mays), and sorghum (Sorghum bicolor (L.) Moench), as it provides effective weed control while minimizing the negative environmental effects associated.
Thermal weed control depends on heat transfer from a hot fluid (air, water, or steam) into the weed plants. The heat flow from a fluid with a temperature of T f to a solid with a temperature of T s is expressed as () q A = h T s − T f where h is the convective heat flow coefficient of the material’s surface (Holman, ).
Flaming, a thermal weed control technique, does not disrupt the soil surface or bring buried weed seeds to the soil surface, and it is less expensive than hand weeding (Knežević & Ulloa, ; Nemming, ; Wszelaki, Doohan, & Alexandrou, ). However, it can be cost prohibitive on larger scales and lower value crops due to higher input costs.

ASCARD. Quality Tools for Vegetation Management Professionals. Sunburst offers the best and most effective thermal weed control tools available anywhere. Our innovative and patented technologies and equipment have been carefully designed and engineered based on extensive field experience with many common vegetation management settings and their requirements, from pioneering infestations of.
Flaming is a thermal weed control method that can kill weeds within and between crop rows using heat generated from propane burners.
Propane flaming should not be a single practice for weed control, other measures are still needed in the tool box of weed management. The aims of this study were to develop custom-built machinery for thermal weed control in container nurseries and to test the weed control efficiency of flame weeding and steaming in Photinia x.
Thermal weed control technology plays an important role in managing weeds in synthetic herbicide-free systems, particularly in organic agriculture. The use of hot foam represents an evolution of the hot water weed control thermal method, modified by the addition of biodegradable foaming agents.
The aim of this study was to test the weeding effect of different five hot foam doses, in two sites. Alternative methods to the use of chemical-synthesis herbicides are alternative organic herbicides and thermal weed control [3,8,9].Nonanoic acid (also called pelargonic acid) is a contact, non-selective, non-translocating, post-emergence non-synthetic herbicide [8,10].It is a fatty acid, which kills plants by destroying the cell membranes, leading to rapid desiccation of plant tissues, and.
What are thermal weed control options. Basically, they’re tools that use heating or freezing to rupture plant cells, which can result in plant death. Lasers, flaming, steam and microwaves are a few examples of thermal weed control, and they’ve been creating a bit of a stir amongst the ag community lately.
Non-Chemical Weed Control. Book • In the recent years, there has been a revival in the development and improvement of thermal weed control to deliver heat for weed management.
Thermal weed control techniques are based on foliar contact mechanisms in which temperatures of approximately °C are applied for the duration of few. FlameWerks' technology has evolved from more than 20 years of innovation and field testing.

Broadcast flaming is a technique that is used for weed and pest control in alfalfa. Alfalfa flaming was a common practice throughout the High Plains in the 's before herbicides and pesticides were available. Liquid propane spray, directed towards the ground, creates combustion at the point of contact.
Weeds only need a 1/10 second exposure to the flame, so pass the flame slowly over the weed. If you are weeding rows in a vegetable garden or along a fence line or drainage ditch, walk slowly (about 1 or 2 miles per hour)(2 km per hour) along the area you want to flame.
Fig. Organic corn that has been flamed for weed control. Flaming kills weeds while doing little damage to the crop. For many grasses, the growing point is below the soil surface where the flame’s heat cannot penetrate effectively to stop or suppress growth.
Flaming as a Method of Weed Control in Organic Farming Systems. Flaming is a thermal weed control method that uses heat to control weeds within or between crop rows. Mechanical cultivation is another weed control method which undercuts weeds between crop rows, while leaving a strip of weeds within the crop row.
A combination flamer/cultivator implement was designed to take advantage of the good qualities of both flaming and cultivation methods to provide a.
Graham Brodie, in Non-Chemical Weed Control, Flaming. Flame weeding is the most commonly applied thermal weed control method. Several kinds of equipment have been developed for weeding, such as tractor-mounted flamers and hand-pushed or handheld devices for weeding around obstacles and for private households.
An alternative weed contol option -- using propane for flame weeding -- is being studied by UNL. Flaming During the flaming process, heat from the flame is transferred to the plant tissues, increasing the thermal energy of the plant cells and resulting in coagulation of cell proteins if.
