Pineapple is a profitable growth crop for many large farming enterprises in Costa Rica. New sweet varieties are expanding the market for the fruit in Europe and Asia.
Paraquat has become essential for post-harvest land preparation. It helps desiccate the tough pineapple crop residues.
The stable fly (Stomoxys calcitrans) provides an additional challenge. It is the most common biting fly pest of confined livestock. Its irritating bites can cause considerable distress to animals and result in reduced production. Heavy infestations...

Paraquat has been used for many years in Cameroon, Africa. Two farmers underline how it has been used safely by everybody on their plantation.
Most of Cameroon’s crops are grown by small landowners, on areas ranging from 2 to 20 hectares, and nearly all are mixed-cropped farms.
Paraquat is a valuable herbicide tool in developing countries benefiting farmers in many ways.
As with all chemicals, including pesticides such as paraquat, care must be taken to minimize human exposure. Provided this care is applied and the...

Paraquat, one of the most widely used herbicide active ingredients in the world for the weed control, was reviewed as part of a periodic re-evaluation of dietary residues under the Joint FAO/WHO Meeting on Pesticide Residues (JMPR) in 2004.
The results of this review were published in the 2004 JMPR report, which stated that:
“The Meeting concluded that the intake of residues of paraquat resulting from uses considered by the current JMPR was unlikely to present a public health concern.”
A complete copy of the 2004...

Pesticide free production (PFP*) is a growing agricultural practice. The designation, which limits the use of pesticides on seeds and plants throughout the crop lifecycle, responds not only to consumer concerns and to grower health concerns related to the use of pesticides on crops but also to the need to reduce costs for growers.
Despite these benefits, effective PFP production faces a serious threat - in the form of weeds.
In an article entitled “Pesticide Free Production: a tool for use reduction,” the author states...

Another weed can be added to the growing list of glyphosate-resistant weeds, according to an article from Western Farm Press published on August 28, 2006.
Author Harry Cline writes:
“Monsanto has confirmed that a Johnsongrass biotype has become resistant to glyphosate in Northeastern Argentina…. A preliminary assessment of the affected area identified the problem on 17,000 to 25,000 acres.”
The article also cites several approaches being used by manufacturers of glyphosate to address the increasing number...

Beijing Municipality, China, is to abolish deep-plow farming and adopt conservation tillage in the next three years. Erosion of topsoil has become a real issue in the region, with severe dust storms resulting in soil loss. Conservation tillage has already been piloted on over half a million hectares of farmland in other Chinese counties, and is also expected to reduce water demand.
Conservation tillage involves leaving the residue of the previous year's crop in the ground to help conserve soil structure. The following crop is then...

Conservation agriculture methods, combined with the use of herbicides, such as paraquat, can save billions of Euros according to a June 29 article in the European Voice.
Entitled “Reducing soil erosion could save billions,” the article outlined study results shared by SOWAP (SOil and WAter Protection). These results show that more than €7 billion in fuel, labor and environmental impact costs could be saved by using alternative farming methods, such as no-till farming, to reduce soil erosion.

The answer is “yes,” according to former Greenpeace leader Patrick Moore. He acknowledges the positive impact of pesticides in a May 2006 article on The African Executive website, saying, “agricultural science and technology have changed our world for the better. Pesticides have played an important role.”
The article, entitled “How pesticides are saving the Earth,” was written in honor of International Earth Day. In it, Moore states:
“…continued research and development in genetic...

Paraquat is helping to create and maintain firebreaks in commercial forests in South Africa.
One of the greatest risks to the long-term sustainability of plantations in South Africa is the risk of fire. Three million tons of fiber from 300,000 hectares of land are produced every year by Sappi Forest in South Africa. As a result, Sappi Forest has developed comprehensive fire control plans, which, among other things, require the preparation, and maintenance of fire breaks during the dry season. Wayne Lotter, Environmental Manager of Sappi...

In the late 1960’s the US government, perhaps in an attempt to deter people from using marijuana, warned that much of the crop had been sprayed with paraquat and was, therefore, unsafe to smoke. However, independent bodies have studied paraquat in this use.
Jenny PronCzuk de Garbino1 stated: "no lung or other injury in marijuana users has ever been attributed to Paraquat contamination".
On this topic, D.P. Morgan states in a US Environmental Protection Agency publication that: "Smoking Paraquat-contaminated...

In March 2006, JMPS published a revision of their first edition of the FAO Manual on development and use of FAO and WHO specifications for pesticides (2006). Within this revised document, some of the key points of clarification are that:
Where appropriate, FAO and WHO specifications should be linked to registration requirements so that they can also be used in the official control of pesticides, to ensure as far as possible that the quality of the pesticide supplied is the same as that registered.

'Sagip-Lupa' means 'save our soil' and that’s just what the Philippines’ Sagip-Lupa Soil Conservation Project is designed to do.
Soil erosion leads to depletion of nutrient content due to loss of surface soil where, unfortunately, most of the nutrients required by plants are found. Farmers in erosion-prone areas often resort to increased use of fertilizers to augment lost soil nutrients.
The Sagip-Lupa project, which began in December 2004, was created to minimize or eliminate the risk of soil erosion on Philippine...

Every living organism needs water to survive, so keeping water clean from pollutants is something that concerns each and every one of us. However, it is an issue of special concern to agrochemical companies and to growers who strive to balance their need for effective weed control with safety for the environment. That’s were paraquat comes in. Comprehensive monitoring around the world confirms that paraquat does not contaminate ground water.
In their RED facts document, the US EPA concluded that “paraquat is not expected or...
