PGRs: Multipurpose Tools for Citrus Improvement

Daniel CooperPGRs, Tip of the Week

By Tripti Vashisth Canopy health of HLB-affected citrus has been directly related to disease severity, fruit drop and overall fruit production. Some success has been found with the use of certain plant growth regulators (PGRs) such as gibberellic acid (GA) and 2,4-dichlorophenoxyacetic acid (2,4-D) to achieve healthier trees with reduced fruit drop and increased production. HLB MANAGEMENT Application of these …

How to Enhance Pre-emergent Herbicide Performance

Daniel CooperTip of the Week, weeds

By Ramdas Kanissery and Robert Riefer Pre-emergent herbicides, also known as residual herbicides, are highly effective in the long-term suppression of weeds in citrus tree rows. These herbicides remain in the soil and prevent susceptible weeds from germinating. In order to achieve the best weed control results, pre-emergent herbicides need to stay within approximately the top 5 inches of soil, …

Irrigation Strategy to Enhance Fruit Growth and Retention

Tacy CalliesIrrigation, Tip of the Week

By Tripti Vashisth  Huanglongbing (HLB) severity is associated with small fruit sizes and lower fruit numbers at harvest. Moreover, small fruit are more likely to drop and drop earlier during preharvest fruit drop. Unfortunately, management practices suggested to increase fruit size or reduce drop have had mixed results. So, before looking for ways to increase fruit size and number, it …

HLB-Affected Trees Use Less Water
