What is effective against anthracnose?

Vera Sergeeva | View Article What do we know about anthracnose? What do we want to know about the disease that would help us to control it? What are the most important steps to improve anthracnose control? A disease is a condition in a plant that affects the plant’s normal functioning or development. For a disease to occur, three conditions must be met. Firstly, a pathogen has to be present on or in the plant. Secondly, there needs to be suitable environmental conditions for the pathogen. Thirdly, the plant must be susceptible to the...
Biological pest control

Biological pest control

Vera Sergeeva | View Article Biological and non-chemical plant protection is important worldwide as an alternative to the use of conventional chemical pesticides. Biological pest control is the use of natural organisms as an alternative to, or in conjunction with, pesticides. It has become well established within protected crops and some field crops around the world. The biological control of pests relies on predation, parasitism or other natural mechanisms. It can be an important component of integrated pest management (IPM) programs. The use of biological control methods can reduce spraying costs and lead to a reduction in the potential for pesticide...
Balanced plant nutrition may help reduce anthracnose

Balanced plant nutrition may help reduce anthracnose

Vera Sergeeva | View Article Some olive varieties are more susceptible to anthracnose than others. Warm and wet weather can further aggravate the problem, leading to infections of epidemic-like proportions. Wet weather makes the application of chemical treatments difficult, so it is important to consider the use of other cultural practices for controlling disease, such as selection of cultivar type, pruning, irrigation and fertilisation. Correct variety selection, planting density, irrigation scheduling and balancing the physical and biological properties of the soil are all crucial to producing a highyielding, quality crop. However, the proper nutritional management of olive trees is also very important. The essential nutrients extracted from the soil and required by the plant in relatively small amounts are called ‘minor...

The influence of pruning methods on insect and disease control

Vera Sergeeva and Michael Thomsett | View Article Insect pests and diseases in the olive grove have significant impacts on production and overall tree health, which if not managed with sound horticultural practices can result in significant economic loss to the grower. Olive trees are susceptible to a wide range of pests and diseases, including black scale, olive lace bug, peacock spot, cercosporiose and...
Anthracnose and Queensland fruit fly in olives

Anthracnose and Queensland fruit fly in olives

Vera Sergeeva | View Article Anthracnose is an important olive disease, causing fruit yield losses and poor oil quality. Damage caused by the anthracnose fungi Colletotrichum species (C. gloeosporioides and C. acutatum) mostly occurs under conditions of high humidity and warm temperatures. This is most noticeable and severe when these conditions occur as fruit is...
