Ginkgo biloba, its seeds that is white fruit can be used as medicine, there is nourishing yin and kidney, lungs and cough, asthma and insect control effect, common diseases are ginkgo stalk rot, mildew, leaf blight, dry blight, ginkgo large silk moth, peach aphid, Leafworm, Ginkgo leaf roller moth, cardamom, tea-yam, etc.
First, stalk rot: The disease is mainly harmful to 1-2 years old seedlings, under high temperature conditions, is the main reason for the induction of stalk rot. Seedlings are damaged at high temperature, disease resistance is weakened, the bacteria grows and reproduces quickly, and the disease is caused by invasion from the seedlings' wounds. In addition, the nursery is low-lying water, and poor growth of seedlings is more likely to occur. Severe onset of hot weather in June-August.
Early sowing, to increase the degree of lignification of seedlings before the onset of high temperature season, enhance resistance to stalk rot, and nursery soil disinfection, appropriate shade, timely irrigation. In the early stage of disease, 50% thiophanate-methyl 1000 times was used for prevention and treatment.
Second, mildew disease: damage the ginkgo kernels in storage, the temperature of about 20 °C, humidity spread conditions, the incidence of immature or broken seeds more.
Seeds must be fully matured and harvested while avoiding seed coat damage. Before storage, it should be fully dried, pick up the seeds and seeds, keep the storage room cool, and pay attention to ventilation. Before storage, soak in seeds with 0.5% potassium permanganate solution for 30 minutes, or disinfect with 10% diluted with 40% formaldehyde.
III. Leaf Blight: Pathogens mainly overwinter on deciduous trees, and spores form in March of the following year to infect new leaves. Seedlings are onset in early June and are onset in August-September. The incidence of common seedlings is higher than that of big trees.
Strengthen management, remove fallen leaves, and fertilize properly. Reasonably planting tree species to prevent interbreeding with Metasequoia, pine, tea, and grapes. Saplings and big trees were treated with 40% carbendazim 500 times in the early stages of early July. The seedlings were controlled from about the beginning of June to the end of August. 0.5% potassium dihydrogen phosphate and 0.2% urea were added simultaneously. Spraying enhances its resistance.
Disenia: Bacteria invade trunks or shoots from wounds and form irregular lesions on smooth bark. With wind, rain, insects and birds spreading, new lesions appear on the trunk after May, and the onset of disease is from July to September.
Protect trees, prevent wounds, increase tree vigor, and increase resistance to disease. Remove severely diseased plants and diseased branches and burn them out in time. Branches or branches on the lesions, after scraping with 10% alkaline water smear, the effect is very good.
Fifth, ginkgo silkworm moth: for large moths, 1 generation occurred in 1 year. The larvae feed the leaves. Newly hatched larvae have social habits. The 1-2 instar larvae can feed from the leaf margins, but the food intake is very small. After the 4th instar, the animals are dispersed and the food intake is gradually increased. After the 5th instar larvae enter the gluttony, they can eat all the leaves.
From August to September, black light traps the adult. The clustered leaves were removed before the third instar larvae. In severe cases, spray 2% deltamethrin 2500 times or 90% dipterex 1500-2000 times in the young larvae.
6. Taoyuan: 1 generation occurred in 1 year. After hatching, the larvae first crawl for a short distance, and then enter into the nuclear hazards. All of the seed nucleuses are eaten or only a part of the seed nucleus is eaten. One larvae and one larvae only feed on one seed.
When the first generation of adult eclosion was treated with 80% dichlorvos 1000 times. The hatching period of eggs can be sprayed with 40% Caesaresporum 1000 times, 7 days after the second spray, to kill eggs hatch larvae.
Seven, dead leafworm: adult worm sucking fruit juice, ginkgo fruit loss within 3-10 days that fall off. The eggs are prolific in the back of the leaves of the host, such as Tongcao and Mahonia, and the larvae mature into the earth after being cooked.
Eradicate the host plants such as pass grass and madam around Ginkgo biloba. 50% trichlorfon 500 times was sprayed from the beginning of May to the middle of June. After 10 days, it was administered once. The best effect was in the evening.
VIII. Ochreophagus thrips: Adults and nymphs all harm the seedlings and the leaves of adult trees. They suck juice on the back of the leaves. After consuming the leaves, the leaves quickly bleed. In severe cases, the leaves are wilted and lead to early defoliation. The drought conditions are suitable for the occurrence of thrips. As the temperature rises, it turns from seedlings to big seedlings and big trees.
Hummer is poor in drug resistance, and it is easy to receive the effect of spraying in time. In the high-frequency period from June to August, 80% of dichlorvos were used to prevent and control 1000 times of liquid, and even sprayed twice, with good results.
Nine, ginkgo ultra-small roller leaf moth: larvae into the shoots harm the new shoot that year, resulting in dead branches, fallen leaves, fruit drop. The worm has a hi-light characteristic, and the weight around the forest edge is greater than that within the forest. The degree of occurrence is closely related to the temperature. As the altitude and latitude increase, the annual average temperature decreases, and the population density decreases.
Adults were treated with 2.5% of deltamethrin 2500 times before emergence. In the early stages of larval hatching, the damaged shoots were sprayed with 800 times 80% dichlorvos EC.
Ten, soybean meal: larvae into the nuclear hazards, and there is a risk of transformation habits. In serious cases, the nucleolus are eaten, leaving only insects in the seed nucleus, which seriously affects the yield and quality of ginkgo seeds. Due to the larvae drilling into the soil, its occurrence is closely related to the soil moisture and texture. Rainfall occurs when the larvae are numerous and the soil is firm.
No other legumes are planted around to reduce the risk of transfer and reproduction of soybean meal. In the adult period, 50% dichlorvos or 90% trichlorfon was sprayed 800 times, and the second time after 10 days, it had a good effect.
