How does eucalyptus control termites?
How does eucalyptus control termites? Please introduce that the common pests of eucalyptus are soil termites, mainly black-winged termites, followed by yellow-winged termites. Although other ant species have been found in the forest, they are not enough to cause harm. 1. The law of harm. In the young eucalyptus forest, termites first harm the root neck, then gradually turn from the soil layer to the surface and aboveground parts, and then strip off the main root, the inverted root, and the basal cortex of the trunk along the topsoil, so that the nutrients of the young trees can not be transported up and down. In serious cases, a "mud quilt" is built up and down the trunk, wrapping all the branches of the trunk, making each young tree look like a "clay sculpture". Termites strip off the phloem of eucalyptus trees in the "mud quilt", exposing the xylem, resulting in the death of the trees. 2. Prevention and control methods. Give priority to prevention, bait and kill. (1) when afforestation, fill the hole with 3-4 grams of carbofuran (carbofuran) mixed with base fertilizer and soil, with 0.35 kg per mu. (2) after afforestation, 2 grams of carbofuran (carbofuran) is applied along the tree tree circle at a horizontal distance of 5 from the tree tree, 0.22 kg per mu. Be careful not to put the powder in contact with the tree seedlings to avoid drug damage. Click to get more eucalyptus planting techniques click to get more flower planting techniques
