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.

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.
