Lettuce is the world’s most popular leafy vegetable. Various types of lettuce are cultivated worldwide, primarily for the human consumption of their fresh, succulent leaves.
During the growing period, farmers face several lettuce diseases that destroy yields and reduce crop quality. Without proper prevention methods and regular crop inspection, these diseases can cause severe damage, and destroy the entire yield. The most hazardous disease is a root rot caused by various fungi from the Pythium family.
Pythium species are soil inhabitants which exist and thrive in most agricultural soils for extended periods of time, especially if the soil is wet. Pythium is easily spread by water flow from irrigation, flooding, and movement of soil by tractors and equipment. It can occur during nearly every crop stage throughout the entire vegetation season. Many farmers forget to observe the crop’s root system, where the first signs of this pathogen occur. There are often no visible signs of pest attack on leaves until significant injury and/or death occur.
Pythium behavior and disease symptoms
There are several symptoms that farmers need to pay attention to in order to determine whether their lettuce is infected with the Pythium species:
Symptoms of the disease become most apparent after thinning at the rosette stage.
Pythium root rot is difficult to control once the infection occurs. Every effort should be directed toward preventing the disease. The following management practices should be considered:
How can Agrivi farm management software help with the Pythium disease?
It is important for every farmer to have complete control over his crop production. Agrivi farm management software allows him to record and track all the activities in their fields. This includes the used amounts of pesticides, fertilizers, work hours of workers and other data. When a profitable crop production is in focus, a farmer needs to properly manage various farm activities, such as crop protection and accurate farm practices.
Agrivi software also gives farmers a knowledge base in the form of tasks, which guide them what to do during a certain vegetation season. Based on the weather forecast for each field, the software alerts farmers of possible pest and disease attack and gives them the list of active substances to treat the pest with.
Manage your farm the easiest way; avoid yield losses and protect your crops on time with the Agrivi software.
