Management of Root Rot in Avocado Trees

Abstract: -Root rot (Phytophthora cinnamomi Rands) is one of the most restrictive factors to avocado growing in main producing regions worldwide. In Brazil, scientific reports on the effectiveness of control methods are scarce. The objective of this study was to evaluate the efficiency of gypsum applications and dolomitic limestone to the soil and potassium phosphite sprays in controlling this disease in 'Hass' avocado, grown without irrigation. The application of dolomitic limestone or gypsum alone is not effective to … Show more

“…Root growth was measured every two weeks, in soil samples collected from 5 tagged trees of each cultivar, at four points under the canopy, distant 0.5 m from the trunk, using a stainless steel probe with 0.07 m in diameter, that was drilled into the soil to a depth of 20 cm (Silva et al 2016). White and unsuberised feeder roots with < 5 mm width were washed out of the soil, dried and weighed.…”

“…O mercado do abacate no Brasil está em expansão e por isso tem atraído produtores rurais de diversas regiões do país, que buscam a diversificação da produção e, também, muitos investidores nacionais e internacionais. Entretanto, mesmo contanto com as condições edafoclimáticas favoráveis para seu cultivo, a expansão da abacaticultura no Brasil tem sido limitada à uma série de fatores, dentre eles, as doenças de solo e da parte aérea, que afetam as principais etapas de seu desenvolvimento (SILVA et al 2016;BROGIO et al, 2018).…”
