Paraquat herbicide for non-selective weed control in no-till and other sustainable agriculture systems
Monday, 14 May 2012

Using paraquat for weed control in oil palm plantations can address a number of the criteria for sustainability defined by the Roundtable on Sustainable Palm Oil (RSPO). These include protecting soil and water quality, and reducing erosion. As part of a wider approach, smallholders undergoing RSPO certification are being shown how to grow more profitable crops while using all inputs more effectively and safely.
Worldwide, 33% of palm oil is produced from crops grown by smallholders. In Thailand, however, smallholders supply 70% of the palm oil produced in the country, so this important group of growers has been a focus of attention for improving sustainability1.

Facts about Thai oil palm smallholders

120,000 farmers in Thailand grow oil palm
98% of these are smallholders
76% of land under oil palm in Thailand is cultivated by smallholders
7 hectares average holding size
70% of production is supplied by smallholders

Oil Palm (Elaeis guineenis) is the leading crop in the global production of vegetable oil. It provides by far the highest yields per hectare, typically 5 to 10 times that of crops such as soybeans, sunflower and canola (oilseed rape). Palm oil also has the particular quality of being a saturated fat and semi-solid rather than liquid at room temperature.

Paraquat’s distinctive behaviour in soil means that farmers around the world confidently use it to protect their crops. Paraquat provides fast broad-spectrum weed control only through foliar contact action. There is no crop damage via the roots or any effect on seed germination. Soil fauna and microorganisms are not affected and there is no leaching or run-off from the degrading paraquat residues reaching the soil.
A new in-depth feature article added to the Knowledge Bank explains the fate of paraquat in soil and what the implications are for the environment and paraquat...

Paraquat’s famous fast speed of action has been captured by a time-lapse video produced by Ohio State University, USA. No herbicide acts faster than paraquat and across such a broad spectrum of weed species too. Fast action gives farmers important benefits including opportunities for higher yields and better prices through earlier planting; rainfastness within 15-30 minutes; and ease of seeing where weeds have been treated after a break in spraying operations.
Ohio State University chose giant ragweed (Ambrosia trifida) as the target for paraquat in this video1....

Cotton is one of the world’s major crops and particularly important to the economies of many developing countries. Cotton itself is a fibre which protects the seed of the cotton plant, much as the flesh of an apple protects the pips. So, fruit are not only for eating. The crop has been at the forefront of the revolution in biotechnology, being the second genetically modified (GM) crop to be introduced in broadacre agriculture after soybeans in 1997.
One of the main traits in GM cotton is tolerance to applications of the non-selective herbicide glyphosate. The choice of...
