Edge fields with planting carried out in the direction parallel to the farms’ border have a lower incidence of greening compared to border plots with perpendicular plantation. This is what stands out a research carried out by the biologist Luiz Henrique Montesino, coordinated by the researcher of Fundecitrus Renato Bassanezi.
The research was carried outin eight farms of different cities in the state of São Paulo, 16 pairs of neighboring plots with the same variety, age and spacing, one planted in the parallel direction and the other in the perpendicular direction. In each field the number of plants with greening from the property currency up to 160 m inside the field was evaluated. As a result, farms with parallel planting showed on average 23% less diseased orange trees than the stands with perpendicular planting.
“Planting parallel to the border of the border plots facilitates the spraying of the border strip, corresponding to the first 100 m from the border, where most of the psyllids are concentrated, and makes it difficult for them to enter the orchards. In new plantations, the recommendation is, when possible, to plant parallel to the currency, “says Fundanecitrus Bassanezi.
