Movement and Toxicity of Nematicides in the Plant Root Zone (4861 words) |
 | The variability of the distribution of the nematicide in soil depends upon the degree of incorporation and the extent to which the chemical is redistributed in soil by diffusion and leaching in soil water. |
| Nematicide dispersal may be severely restricted due to the reversible and irreversible binding (adsorption) of nematicide molecules onto organic matter surfaces. |
| Nematicide application rates required for effective nematode control may be determined by the extent to which nematicide adsorption to soil organic matter occurs, the volume of treated soil which is determined by soil type and soil moisture content. |
| nematicide history (4173 words) |
| Ancient history of nematicides is closely associated with the early history of soil insecticides, and probably had its beginning about 1854, when Garreau recognized the insecticidal value of carbon bisulphide (also spelled disulphide and bi- or disulfide). |
| The end of the medieval era of nematicide history and the beginning of the modern era was marked by the publication in 1943 of a paper by Dr. Walter Carter, of the Pineapple Research Institute, Honolulu, Hawaii. |
| Nematicides are now regularly used by growers of many crops once considered to be outside the profitable range. |
