(1) Tea cake disease Tea cake disease occurs in tea gardens in Sichuan, Guizhou, Yunnan, Guangxi, and Guangdong tea regions, and it is an important budding disease in tea trees. After the damage, not only the yield, but also the bitterness and fragility of the tea, the quality of the tea was significantly reduced.
[Identification]
Mainly damage young leaves and shoots. First, light green, yellowish or reddish transparent dots are generated on young leaves, and then gradually expand into round lesions, and the color becomes light yellowish brown or dark red. The lesions are recessed on the front and the backs are raised with grayish or pink powder. In the end, the powder disappeared, and the convex part shrunk into spotty, with a grayish-white edge and a cake-like shape. After the midrib or edge of the leaf is infected, the diseased leaf often twists and deforms. Sometimes there can be as many as a dozen lesions on a blade.
[The law of occurrence]
The disease is caused by fungi. The wintering of the mycelium in the living tissue of the diseased leaf. Under suitable conditions, Qichun develops spores, spores fly away with the wind, infects new tissues, and produces new spores that continue to re-infect. The disease is a low temperature and high humidity disease. Under conditions of low rain and sunshine, diseases are easy to occur and prevalent. The peak of April-May and September-October occurs throughout the year.
[Control methods]
1 Strengthen the quarantine of seedlings and control the transfer of tea seedlings from the wards.
2 In the early stage of disease occurrence, when the incidence rate of shoot tip reaches more than 35%, 25% triadimefon, 75% tridemorpholine, or 25% Versitrix 1000 times can be used to control the spraying of the canopy.
Tea leaf blight is one of the most common diseases found in tea plants and is distributed throughout the country. The weakening of the tree vigor and the serious occurrence of Taiwan’s tea plantations have caused the tea plantations to be brownish.
[Identification]
The disease mainly damages the leaves. Lesions occur at the tips or edges of old leaves and into leaves, yellowish-brown water stains are initially formed, followed by dark brown, grey and white irregular shaped patches, with wavy ring veins on the lesions, resembling moire patterns. Gray and black flattened round spots appeared on the late lesions and arranged along the ridges.
[Occurrence law]
The disease is caused by fungi. Mycelia or conidia discs overwintered on diseased trees or fallen leaves. The conidia were formed in late spring and the spores spread with the wind and rain to promote the spread of the disease. The disease is a kind of high temperature and high humidity disease. From June to late August to early September, the most prosperous event occurred. The tea gardens with high groundwater levels, poor soil, and weak trees are prone to disease.
[Control methods]
1 Strengthen the management of tea gardens, increase fertilization, diligently remove weeds, and increase the growth potential of tea plants.
2 In the tea gardens with severe disease on a perennial basis, spray protection is available at the early onset of the disease. 75% chlorothalonil, 50% carbendazim 1000-fold, and 70% thiophanate-methyl 1500-fold can be used for spray control.
Tea Leukoplakia White spot disease is mainly distributed in high mountain tea gardens in the tea regions of Zhejiang, Anhui, Fujian, Jiangxi, Guizhou and Sichuan. It is an important budding disease. Damage leaves and shoots, into the tea fed bitter, soup color, odor, production and quality decreased significantly.
[Identification]
The disease mainly damages young leaves, new shoots and young fruit, and has acicular brown dots. It gradually expands into round lesions, grayish white, and has a central depression with dark brown or purple-brown ridges on the edges and scattered black particles on the edges. . When severe, as many as several hundred lesions on the leaf blade fuse with each other to form an irregular large spot, resulting in abnormal growth of the leaf blade and premature shedding.
[The law of occurrence]
The disease is caused by fungi. Wintering in diseased tissue with mycelium or medicated robes. In late spring, conidia are produced and spread with wind and rain. The disease is a disease of low temperature and high humidity. The temperature is 16-24 degrees Celsius, and the relative humidity is more than 80%, it is easy to develop; when the temperature is higher than 25 degrees Celsius, it is unfavorable. The onset period is in spring and autumn, and alpine tea gardens are suitable for onset.
[Control methods]
1 The timely collection of tea in batches can reduce the source of infection and reduce the incidence of disease.
2 Perennial tea gardens can be used in the early spring tea, use 75% chlorothalonil 8OO times, 70% thiophanate-methyl 1500 times, 50% carbendazim 1000 times spray control.
The root-knot nematode disease of tea root-knot nematode disease is distributed throughout the country. Damaged young roots of tea seedlings.
[Identification]
The disease is 1-2 years old seedlings or cutting roots. After onset, nodules are formed on the main and lateral roots, and the surface is rough, brownish, and the roots are malformed, often without fibrous roots. The upper part of the diseased plant leaves are yellow, the plants are short, and when they are serious, a large number of fallen leaves, and even the whole plant withers.
[The law of occurrence]
The disease is caused by a lower animal nematode. Adult females and eggs live in the nodule, or larvae in the soil. The spring eggs hatch into larvae. The larvae parasitize the root system, sucking nutrients and secreting irritants to form nodules. The root-knot nematode is often parthenogenetic and spreads in the soil depending on its own activities. It can also be propagated by seedlings over long distances.
[Control method 1 used disease-free seedlings and did not introduce tea seedlings from the wards.
2 Soil disinfection should be performed on perennially seedbeds or seedlings. On the one hand, the soil can be deeply turned in midsummer and the nematodes can be exposed to exposure to the gentry; on the other hand, 3% of carbofuran can be used for 2-3 kg or 10% per mu. Line 0.5 kilograms per acre with fine soil Mix well and apply 8 cm deep ditch for soil treatment.
