Peony in Hezhou - Pest and disease in Tianmendong and its prevention
When we cultivate Tianmendong, will we often be confused by the insect plague questions of Tianmendong, and today I will introduce the disease and pest incuracies and prevention methods of Tianmendong.
Insect infestation and its control in Tianmendong
There may be red spider damage during the growth process of Tianmen winter, red spiders will first eat the leaves of Tianmen winter, and there will be red spiders in the simplest time of May and June of the year, so in May and June, we must pay attention to investigating the leaves of Tianmen winter to see if there are red spiders.
So how do we control red spiders? First of all, in the winter, we must do a good job in prevention and control, in the winter, the branches and leaves that fall in the winter of Tianmen will be sorted out and cleaned, and they can be buried deeply and can be burned, and if the family cultivates, the dead leaves will be sorted out and thrown away. When we find that there are red spiders on the leaves of Tianmendong, we can use the insecticide that is more useful, diluted according to the instructions, and regular spraying can be useful to kill the red spider.
Tianmen winter will also attract aphids, aphids first of all eat the young shoots and young vines of Tianmendong, and the severe aphid plague will shrink the vines of Tianmendong. If the time of the aphid infestation is still in the early stage, the insecticide can be used to kill the aphid, but once the aphid infestation is very severe, we must directly cut off the vine that has aphid infestation and apply some fertilizer together, so that in about twenty days new bud vines can grow.
Diseases of Tianmendong and their prevention and control
Apocrypha contrasts the disease simply presented when root rot. Root rot occurs from the root, the comparison is not simple and timely found, root rot is gradually developed from the tip of the root to the inside, and finally all the roots will rot, and the inside will become a paste. The main reason for the onset of root rot in Tianmen Winter is that the soil is too wet or the roots are bitten by pests, and the bruises at the time of fertilization on the soil may also be caused. Therefore, we usually pay attention to drainage operations when cultivating Tianmendong, and sprinkle quicklime powder around the Tianmendong plants that have root rot. This can play a sterilization effect and cure root rot.
