Beware of the spread and harm of silkworm

Last summer, a strange leafless rattan plant was like an “extraterrestrial visitor”. It appeared in the peasants’ orchards in Qinggu Village, Wangxian Township, Wanrong County. This filiform rattan plant clings to the tree like a “beautiful snake” and quickly populates the canopy. The early leaves of the tangled fruit trees were yellowed, the shoots were dry and the nutrients were exhausted in the later period, and the whole plant died.

What's even more frightening is that after the plant has cut its rhizomes, it still bolds and spreads. Because it will be filled with suction cups at Leoch, linked to the boughs of fruit trees, screens and ducts on the xylem, and they will be taken directly from the tree for their own enjoyment. In fact, it has merged with fruit trees.

In order to eliminate the farmers’ panic, the author found out that the plant was a quarantine vicious parasitic grass. Its scientific name was Dodder seed, and its stems were finely filamentous, yellowish-white or orange-yellow, and they depended on the nutrition of the tangled plants to survive. The "Vampire" is called. In general, herbicides cannot be sprayed because they cause phytotoxicity. It takes a lot of headaches to remove the artificially time-consuming and laborious trees.

The authors found that this parasitic grass did not grow locally. Most of these fruit farmers have been victimized by the use of cattle and sheep dung from foreign markets. The seeds of Dodder seed are mixed in animal dung, and when they encounter a suitable environment, they breed wildly.

The author suggests that the majority of farmers should establish a scientific view of fertilization. Jishi farmyard manure, especially cattle and sheep manure in other places, must be thoroughly fermented and cooked to kill harmful seeds and eggs. The orchard that has been infringed must be checked frequently from May to October to remove the seedlings of the dodder seedlings or cut off the parasitized shoots and burn them in a concentrated manner; industrial organic fertilizers such as the Orford bacteria tribe, protein family, and granule can also be used. Avoiding damage; in addition to strengthening quarantine, the plant protection department should stock special herbicides for Cuscuta to prevent its widespread outbreaks.
