certainly not a new concept to the citrus industry. For more than five decades, foliar fertilization of citrus has been recommended to correct zinc, manganese, boron, copper and magnesium deficiencies. It is now common knowledge in agriculture that properly nourished crops may tolerate insect pests and diseases. Traditionally, citrus growers try to achieve optimum nutrition through direct soil ...

Florida has a long association with citrus ( Citrus sp.) production. However, the industry in been devastated by Huanglongbing (HLB) or greening disease Candidatus Liberibacter asiaticus). HLB affects tree phloem and eventually causes death. Cover crops, noncash have traditionally used row crop production to improve soil organic matter, for nitrogen fixing, weed control. growers may benefit fro...

Aim of this study was to evaluate the possible application fields of organic agriculture, the province is a grower's perspective. Because of its accurate and appropriate management, soil and products to help reduce the use of chemicals in production and on track to achieve sustainable development, Mazandaran province is a leader in modern agricultural practices and organic agriculture has the p...

In Florida, growers are concerned about the ecological and economic ramifications of being dependent upon insecticide applications for the management of the Asian citrus psyllid, Diaphorina citri, the insect vector of the pathogen which causes Huanglongbing. In collaboration with Florida citrus growers, we have been evaluating approaches that would be more IPM compatible in the long term. In 20...

Professor Hume was right: rootstocks are critical and much is still to be learned. Rootstocks and scions are the foundation of many tree fruit industries of the world. Together, those components establish profitability, but it can be argued that the rootstock is the critical component; otherwise, scions would be grown on their own roots everywhere. There is no precedent for the failure of a cit...

A factorial experiment begun in 1980 included ‘Hamlin’ and ‘Valencia’ sweet-orange scions [Citrus sinensis (L.) Osb.], and Milam lemon (C. jambhiri Lush) and Rusk citrange [C. sinensis x Poncirus trifoliata (L.) Raf.] rootstocks, tree topping heights of 3.7 and 5.5 m, between-row spacings of 4.5 and 6.0 m, and in-row spacings of 2.5 and 4.5 m. The spacing combinations provided tree densities of...

When it comes to keeping the world green, roots have historically been considered to be mere purveyors of water and nutrients to the shoots. However, this view has changed dramatically over the past 25 years as evidence has accumulated that roots can be the ‘movers and shakers’ in orchestrating aboveground interactions between plants and their panoply of parasites (Bezemer and van Dam, 2005; Er...

Abstract The planting of new types table citrus is an interesting alternative for growers in the state Paraná, as this domestic market continues to grow and needs innovation. Thus, aim study was evaluate acceptance storage a hybrid region Londrina / PR, Fremont IAC 543 mandarin (Citrus clementina hort. ex Tan x C. reticulataBlanco). Treatments were: fruits with without wax coating at room tempe...
