What to Do About Sesame Lodging? Cause Analysis and Control Measures

We are all fairly familiar with sesame, which can be divided into white sesame and black sesame, and their cultivation also differs somewhat; in daily life we come into contact with black sesame more often. During sesame cultivation, lodging can occur, severely harming yield and quality, so how should sesame lodging be controlled? Let's take a look.

I. Causes of Lodging

The main reason is poor lodging resistance of the variety. Some varieties have taller stems and weaker fibrous tissue in the stems, and are themselves fairly tolerant of poor soil; once in an environment with sufficient fertilizer and water, their stems grow rapidly but are not thick enough, and lodging occurs. In addition, improper management, such as excessive moisture at the seedling stage, can produce tall, spindly seedlings; excessive density; poor aeration; and excessive nitrogen fertilizer application all cause the plants to grow excessively with thin, weak stems, making them highly prone to lodging. In addition, severe disease is also a factor that can cause lodging, and failure to control stem-boring insects in time can also cause lodging.

II. Control Measures

1. First, choose varieties with strong resistance to pests, diseases and lodging, which can greatly reduce the occurrence of lodging.

2. During planting, carry out intensive cultivation and deepen the plough layer to create a good soil environment for the sesame root system; this is also one of the main measures for controlling sesame lodging.

3. Plant at a reasonable density to improve field aeration, so that the plants grow robustly with thick, strong stems.

4. Maintain a balanced ratio of nitrogen and phosphorus to avoid one-sided application of nitrogen fertilizer, which causes excessive vegetative growth.

5. Pay attention to pests and diseases to prevent them from causing the stems to break and fall over.

6. Plant growth regulators can be used to promote rooting, check seedling growth and control vegetative growth, so as to avoid the phenomenon of tall stalks and weak stems.

7. Carry out drainage measures properly on cloudy days to prevent excessive vegetative growth; water promptly in drought, but never flood-irrigate, so as to avoid causing lodging.
