What are the specific drugs for killing rice red nematode?

To kill rice red nematode, carbosulfan or carbaryl or chlorpyrifos granules can be used, 29% high-chlorine dichlorvos EC 70ml / mu can be evenly scattered, and 28% rice Lefeng water agent 80ml / mu can be sprayed with 15kg water. The following is an introduction about red nematode for everyone to understand.

Introduction to red nematode

1. Distribution of red nematodes

Red nematodes, also known as filamentous earthworms, water earthworms, red filariasis and red nematodes, are often distributed in the shallow waters of river branches and muddy ponds. Most of them live on the banks of river ditches or in the sludge at the bottom of the river, concentrated on the surface of the sludge, one end is fixed in the sludge, and the other end extends the sludge to quiver in the water. As soon as they encounter alarm, they immediately withdraw back to the sludge.

two。 The value of red nematode

Water earthworms are mostly used as fodder for goldfish, koi and river eel seedlings in the south, and the price is high. Moreover, red nematode has rapid reproduction and high nutritional value (62% of crude protein in dry matter, 35% of essential amino acids and 98% of nitrogen recovery). It is a favorite food for many aquatic animals in the seedling stage. it is also the main food for benthic fish such as Sturgeon, mandarin carp, crucian carp, Loach, baby fish and rice field eel.

3. The harm of red nematode

Because of its own bacteria and its excreta, red nematode can cause gastrointestinal discomfort, leading to diarrhea, nausea, vomiting and other symptoms. At the same time, it acts as an "indicator" of unclean water. Its existence shows that some link of tap water has been organically contaminated in the process of transportation.
