After June, Ginger grew well as a whole, but I still found some minor management problems to share with you.
Continuous high temperature, many ginger shed from 11:00 noon to 2:00 p.m. are more than 35 degrees, here I still want to remind Jiang Nong friends, pay attention to the wind cooling, Jiangdi drought attention to watering in the evening.
1. Pay attention to the occurrence of thrips and borers.
If there is no control, it is best to carry out chemical control before 10. Hazard symptoms and occurrence rules have been mentioned in previous articles, the control method can be ethyl doxycycline (Alice) 1000 times solution, perchlorothiazide (Alica) 750-1000 times solution or 60% imidacloprid 1500 times with 1.8% avermectin 1500 times spray control.
Two. Ginger neck rot and anthrax disease treatment
Recently, some fields have sporadic neck rot due to management reasons, but some farmers are not clear about the initial symptoms of stem rot and anthrax. I would like to share this with ginger briefly.
1, the symptoms and differentiation of these two diseases:
In the early stage of the disease, the stem and leaf of the infected plant turned yellow, the tip of the near ground leaf turned green and yellow, and then extended to the whole leaf. Stem disease first green at base or leaf sheath, and water stained brown lesion.
Anthracnose occurs at the apex or margin of the leaf at the beginning of the disease. It begins with a watery brown spot, then develops downward and inward as a margin or spindle type. The lesions are moire or obscure moire.
2, prevention and treatment methods:
The rotten neck can be sprayed with 3% Mycoplasma wettable powder 600 times liquid and 25% prochloraz EC 1500 times liquid. Anthracnose can be sprayed 1500 times with 32.5% benzoate.
