Diheteropogon Microterus Clayton

Description of Diheteropogon microterus Clayton

Diheteropogon microterus Clayton is a species of grass belonging to the family Poaceae. It is commonly known as Short-tipped Windmill Grass or in Tagalog as "Tangal-tangal". This species is native to tropical regions of Asia, particularly in the Philippine archipelago. It can be found growing in open areas, roadsides, and grasslands, especially in the lowlands.

General Appearance

Short-tipped Windmill Grass has a clumping habit, and its culms or stems grow up to 30 to 60 centimeters in height. The leaves are linear, flat or folded, and have a length of 4 to 10 centimeters, with a width of 2 to 4 millimeters. The inflorescence is a broad panicle with spikelets on one side, each having 1 to 3 florets. The plant's seeds are 2 to 4 millimeters long and have twisted awns that look like tiny windmill blades.

Uses

Short-tipped Windmill Grass is commonly used in the Philippines for animal forage, particularly as a food source for cattle, buffaloes, and horses. The plant is known to have high nutritional value, containing protein, energy, and crude fiber. It is also often used in land restoration and erosion control projects due to its ability to stabilize soil. Moreover, this plant has been traditionally used for medicinal purposes as it has been known to have diuretic, antiseptic and, antipyretic properties.

Light Requirements

Diheteropogon microterus Clayton requires full sun exposure to grow. It can tolerate partial shade but isn't suitable for heavily shaded conditions.

Temperature Requirements

Diheteropogon microterus Clayton is a warm-weather grass and grows well in tropical or subtropical climates. The optimal temperature range for its growth is between 20°C to 30°C (68°F to 86°F). It can withstand temperature fluctuations to some extent but doesn't do well under frosty or freezing conditions.

Soil Requirements

Diheteropogon microterus Clayton grows well in sandy, loamy, or clay soils. It prefers well-drained and fertile soils with a pH range between 5.5 to 7.5. It's not suitable for waterlogged or poorly drained soils as it may lead to root rot.

Cultivation of Diheteropogon microterus Clayton

Diheteropogon microterus Clayton is a plant that thrives best in arid and semi-arid regions. It grows well in well-drained soils, which are rich in organic matter.

The plant requires plenty of light to grow well. Therefore, it is advisable to place it in a sunny location. However, it can also tolerate partial shade.

Watering and Fertilization

Regular watering is necessary for the plant to thrive. Watering should be done once a week, and the soil should be allowed to dry out partially before the next watering. Overwatering may lead to root rot.

Fertilization is essential for Diheteropogon microterus Clayton to grow well. To ensure healthy growth, the plant should be fertilized once every three months using a balanced fertilizer.

Pruning

Pruning can be done to control the size and shape of Diheteropogon microterus Clayton or to remove dead or damaged foliage. The best time to prune the plant is in early spring before the new growth appears. Regular pruning can help to promote new growth and maintain the desired shape of the plant.

Propagation of Diheteropogon microterus Clayton

Diheteropogon microterus or small-grained feather grass is commonly propagated through seeds. However, it can also reproduce vegetatively through root division.

Seed Propagation

Seeds of D. microterus are small and light, with average dimensions of 1.5 mm × 0.5 mm. The seeds can be collected manually or allowed to fall to the ground naturally. After collection, they should be cleaned of debris and dried to a moisture content of 10% to prevent fungal growth.

The seeds should be sowed during the rainy season in soil with good drainage and sunlight exposure. Seeds can be broadcasted manually or with mechanical seeders. The recommended planting density for D. microterus is 3-4 kg/ha. After sowing, the seeds should be lightly covered with soil, and their progress should be periodically monitored until germination.

Vegatative Propagation

Diheteropogon microterus can also be propagated through root division. This method is ideal for plants that are already established and mature. The root ball should be carefully removed from the soil and divided into smaller sections. The divided roots should then be planted in the desired location with good soil drainage and moisture. Vegetative propagation has the advantage of producing genetically identical plants, maintaining the quality of the parent plant.

Overall, D. microterus can be propagated through either seed or vegetative propagation methods. Seed propagation is suitable for establishing new plants, while vegetative propagation is useful for maintaining an existing population and ensuring genetic uniformity.

Disease and Pest Management for Diheteropogon microterus Clayton

Diheteropogon microterus Clayton is a type of grass commonly found in tropical areas and is known to be quite resilient against pests and diseases. However, there are still some common pests and diseases that gardeners and farmers should be wary of. Here are a few tips on how to manage them:

Common Pests

The most common pests that affect Diheteropogon microterus Clayton are grasshoppers, crickets, and armyworms. These pests can cause significant damage to the plant, often consuming entire leaves or stems. To manage these pests, it is essential to regularly monitor the plant's growth and look for any signs of infestation. If an infestation is detected, insecticides or natural alternatives such as neem oil can be applied to the affected areas.

Common Diseases

Diheteropogon microterus Clayton is also susceptible to a few diseases such as leaf spots, rust, and smut. Leaf spot, caused by various types of fungi, results in small brown or black spots on the leaves and can weaken the plant. Rust, also caused by a fungus, appears as orange or brown spots on the leaves and can spread quickly. Lastly, smut, caused by a fungus, appears as black, powdery growth on the plant's stem and can stunt its growth. To manage these diseases, it is recommended to remove any affected leaves or stems and dispose of them properly. Fungicides can also be applied to help control the spread of the disease.

Overall, prevention is key to managing pests and diseases for Diheteropogon microterus Clayton. Regularly monitoring the plant's growth and practicing good sanitation and hygiene measures can help prevent infestations and the spread of diseases.
