Watch out for glyphosate contamination
FAST FACTS
The herbicide glyphosate can build up in the soil and plant tissues.
Glyphosate contamination is mostly a problem in clay soils with low acidity.
Symptoms of contamination are numerous, ranging from production decline to increased susceptibility to diseases.
Glyphosate is considered an indispensable weed-management tool for both fruit and grain producers. However, it has recently become associated with a number of problems in crop production.
James Dick, co-owner of DNS Crop Institute, says that in certain Grabouw orchards, he has noticed a decline in production, as well as chlorosis and retarded growth in the apical reaches of some trees.
