Pests are always a concern to farmers. Leaf rollers are one of the most common pests that harm rice crops on a large scale. Thus, they should be eliminated promptly so as not to affect the crops.

Agricultural drones are the optimal solution to prevent pests on a large scale for fields. Find out how effective agricultural drones can help eliminate leaf rollers with us.

Leaf rollers harm crops

Conditions to appear

Leaf rollers often appear in cool climates, high humidity, and changeable weather. They usually harm when the rice starts tillering to milking (starts to ripen), especially from August to September.

Manifestations

Leaf rollers harm rice by releasing silk that binds the two leaf edges into a tube. Then they eat the upper epidermis and the parenchyma and chlorophyll of the leaf.

Leaves are sucked up by leafworms, causing poor photosynthesis, and leading to poor growth of rice plants. Therefore, the field is not green, the leaves are silvery white. This leads rice seeds to be small, and flat which affects the yield of the crop.

Measures to prevent leaf rollers

• Sanitize the field regularly to detect and prevent timely from the early worm stage.
• Eliminate weeds, as this is the home of worm larvae.
• Sow rice with appropriate density.
• Take care of proper irrigation and fertilization.
• Use biological measures such as light traps.

Farmers should note that in areas where there are both butterflies and leaf rollers, 100 random leaves should be checked. If 5 leaves are found to have worms, they should be sprayed with insecticides.

Eliminate leaf rollers by agricultural drones

Controlling pests is extremely important because it directly affects the yield and quality of rice seeds. Using agricultural drones to spray pesticides is the most effective and optimal method today.

Agricultural drones can operate at night, under hot sun or rain (no wind). Leaf rollers often bite and harm rice at night, so spraying insecticides by drones is an optimal measure.

With a drone, we only need to control it through a mobile device. It reduces the risk of trampling rice or directly contacting with pesticides. This can protect farmers’ health and the environment. In addition, the drone can adjust the amount of the appropriate pesticide to reduce residues and protect the environment.

The drone is equipped with modern fogging technology with a fast spray speed, helping the pesticide to be evenly dispersed and absorbed quickly. As a result, we can control pests quickly, accurately, and effectively. The agricultural drone has a high spray capacity. For example, the DJI Agras T30 series can spray 16 hectares of fields within 1 hour.

In addition, farmers can monitor the growth of rice plants and the situation of pests and diseases in the field because of the built-in smart map on the device.

Agricultural drones help farmers eliminate pests and diseases thoroughly, and save time, labor, and costs.

Pesticide spraying service nationwide

Spraying pesticides is an essential but labor-intensive step. If sprayed improperly, it can affect farmers’ health and the environment. In addition, nowadays, it is quite difficult to find workers to spray pesticides.

Nowadays, many provinces and cities in our country have deployed pesticide spraying services to help farmers control pests quickly and effectively, ensuring crop yield and rice grain quality. Moreover, the cost of hiring spraying services is also lower than hiring manual spraying workers.

Hope you will find useful information about using agricultural drones to eliminate leaf rollers effectively.
