Tomato: Reduce Chemical Pesticide Input by 50%, Increase Productivity by 14%

Background

Open field tomato cultivation consumes a tremendous amount of pesticides and is a significant concern to many food companies and major retailers in Europe.  In a cultivation base for Heinz tomato in Spain, implementation of colloidal nutrients provided a solution to more sustainable pesticides management.  On a 5 hectares tomato field, 2.5 hectares used OCC colloidal nutrients with only 50% dosage of standard chemical management following the labels’ recommendation.  Another 2.5 hectares plot used standard protocol with a full dosage of the pesticides.  The cultivar variety was Heinz 9661. Throughout the cultivation period, the OCC colloidal nutrient plot showed more vigour in growth.  Following table illustrates the details of the dosages of the two scenarios.

Results

  1. OCC plot yielded 120,000kg/ha at €243/ha of chemical cost, including cost of OCC colloidal nutrient.
  2. Standard plot yielded 105,000kg/ha. at €482.58/ha. of chemical cost.
  3. OCC plot had an average BRIX level of 6.03 and Standard plot 5.01.
  4. No incidence of diseases was observed on both plots.
