Late blight: A fungal disease. The typical symptoms are yellowish-brown or black spots on susceptible leaves, and white molds on the leaves just after the rain or when the dew is dry. Found that the central disease should be promptly removed; early onset of the use of 50% of the use of suspended solids 500 times or 64% of Tianliang WP 500-600 times liquid.
Black shank disease: The most obvious symptom is that the stem base is darkened until it is connected to the virgin potato, and soon it softens and rots, easily pulling out the soil surface. Longitudinal diseased plants show that the vascular bundles have become brown. Potatoes, which are generally severely diseased, have decayed in the field before harvest. Control methods: 1, appropriate increase in nitrogen fertilizer, reasonable irrigation. 2. Once the diseased plant is found, remove it immediately. 3. Remove field potato residues and eliminate sources of infestation. 4. Foliar spray of 0.1% copper sulfate solution or copper hydroxide can significantly reduce black shank disease.
Viral disease: mainly after the onset of wrinkled mosaic disease and roll leaf disease two. Control methods: 1, to strengthen the cultivation and management. Increase the spacing, narrow the spacing between plants, high ridges and furrows, apply basic fertilizers, increase phosphorus and potash fertilizers, reasonably apply water, remove diseased plants in time, and reduce the incidence. 2, control rickets. Immediately after emergence, the potato was sprayed to control aphids. 3, chemical control. With 1.5% of the plant disease Ling 1000 times plus 20% of the virus A 600 times spray, sprayed every 7 days, even spray 3-4 times, better disease prevention.
Ring rot: generally begins to show symptoms before and after flowering, stem shortening, leaf color brown yellow withering, yellowing between veins, resulting in yellow-brown plaques, leaf margin curled slightly upward. The diseased plants should be eliminated in time, and the prevention and control of underground pests should be taken into consideration. Prevention of underground pests using 480 g / l Ino-Eco Oil 500-800 times liquid.
Locust: 2.5% Wan Li Wang No. 1 (or No. 2) diluted 500 times, or diluted 10% in WP 1000-2000 times, 24% in Wan Ling Shui diluted 500 times, diluted in 3% acetamiprid EC 800 times. , 30% Ferguson EC diluted 500-800 times for foliar spray.
Ground tiger: Mainly harm the seedlings, bite off the stem base near the ground, and make the plant dead. Prevention methods: 1, fall, autumn, destroy their wintering sites, can kill a large number of larvae and eggs, reducing the overwintering base. 2, cultivating insect pests. Eradicate the weeds at the edge of the field and the fields. 3, set the molasses trap or black light trap adult. 4. Chemical control: 480 g/L 500-800 times of Ino-Emulsion or 30% of Ferguson (acetophos) 500 times.
Potato tuber moths: Insect-free seed potatoes are used to avoid continuous cropping of potato and tobacco crops. Clean the pasture, combined with cultivating the soil in the cultivator, to avoid the exposure of the potato block to adult oviposits. In the epidemic period of the onset of damage to the generation of adults, use 4.5% Lubrifoam 1000-1500 times or 24% Wan Ling agent 800 times.

Tuberculosis (TB) is a potentially fatal contagious disease that can affect almost any part of the body but is mainly aninfection of the lungs. It is caused by a bacterial microorganism, the tubercle bacillus or Mycobacterium tuberculosis.Although TB can be treated, cured, and can be prevented if persons at risk take certain drugs, scientists have never comeclose to wiping it out. Few diseases have caused so much distressing illness for centuries and claimed so many lives.
