Control methods of Dragon Blood Tree Tip Blight

Dragon blood tree tip blight is mainly harmful to the lower leaves. After the leaf tip is infected, the leaf tip expands into the leaf, the disease spot becomes straw yellow and sunken, there is a brown line at the junction between the disease and health, and there are many small black spots in the disease. Leaves often die of disease, but the middle leaves die only at the tip, so it is called tip blight. Therefore, it has a very direct impact on the viewing effect.

Dragon blood tree tip blight is a facultative parasite, which often remains on the diseased leaves of dragon blood tree or on the diseased fallen leaves on the ground. the spores of the pathogen are released under the condition of high humidity and carry out primary infection and repeated re-infection by means of wind and rain transmission. Rain Water is an important condition for the occurrence of the disease. It is easy to occur when it rains for a long time.

Prevention and control methods of dragon blood tree tip blight:

(l) breeding resistant varieties or using resistant varieties as grafting materials.

(2) careful maintenance to improve disease resistance.

(3) it is necessary to do everything possible to reduce □ injury during transportation.

(4) if necessary, spraying l:l:l00 double Bordeaux solution or 53.8% can kill 2000 times of dry suspensions and 3000 times of 10% high water dispersible granules.
