Since 1974, culm brown rot of Phyllostachys viridis has been found in Nanjing, Li Yang County of Jiangsu Province and De Qing County of Zhejiang Province. In the field the disease infects Ph. viridis (Young) Mccl. and Ph. viridisf. houzeauana (McCl.) C. D. Chu et C. S. Chao only. Violet-brown to black-brown streaks occur at the bottom of the infected culms and gradually gird them, causing death of the host finally. After a series of isolations and inoculations, the pathogen of the disease has been identified as Fusarjum solani (Mart.) Sacc. In artificial inoculation the fungus can be made invaded through wounds. At the daily mean temperature of 22 -25℃ the incubation period takes 15-20 days. The optimum temperature for fungus growth aud spore germination is 25-28℃. IT grows normally with a pH randging from 4.5 to 10.0. By artificial inoculation, infection spread to Phyllostachys pubescens Mazel ex H. de Lehaie, Ph. bambusoides Sieb. et Zucc., Ph. glauce Mccl. , Ph. praecox C. D. Chu et C. S.

Bamboo-culm rust is an important disease of bamboos.It has become more common since 1970s in bamboo areas of Zhejiang and Jiangsu provinces, making many bamboo forests on the verge of disintegration. Through observation this disease is found to appear mostly on the lower or basal parts of culms, severely spreading to the upper parts or branches, and sometimes even on the diseased branches and emerging skip rhizomes.The rust comprises of three periods of telia, summer-born spore masses, yellow spots, among which...

Bamboo-culm rust is an important disease of bamboos.It has become more common since 1970s in bamboo areas of Zhejiang and Jiangsu provinces, making many bamboo forests on the verge of disintegration. Through observation this disease is found to appear mostly on the lower or basal parts of culms, severely spreading to the upper parts or branches, and sometimes even on the diseased branches and emerging skip rhizomes.The rust comprises of three periods of telia, summer-born spore masses, yellow spots, among which the yellow spot period is usually ignored but it can cause other diseases on basal culms and even the die off of whole culms. The inoculation test indicates that winter-born spores-sporidium do not infect culms and shoots.From May to June summer-born spores are discharged and infect new culms of the very year and old ones from the wound. Bamboo-culm rust has occurred widely in bamboo areas of Zhejiang province with more than 16 species being parasitized.It has brought great lose to bamboo growth and shoot production.Therefore more attention should be paid on its control.

竹秆锈病(Stereostratum corticioides (Berk et Br.)Magnus)又称竹褥病。七十年代以来,江、浙一带的竹秆锈病有所蔓延,病情逐渐加剧,许多地方的竹林已到毁灭的地步。对该病进一步深入研究,寻求彻底的防治措施十分必要。据定点多年观察,该病多发生在竹秆的下部或基部,严重的蔓延至竹秆的上部或枝条上,甚至发生在竹丛枝病的枝条和地面的跳鞭上。病害的冬孢子堆、夏孢子堆、黄斑三个时期较为分明,以往人们对黄斑这个症状往往忽视。竹秆上病斑多时,将诱发其它竹子秆基病害或全株死亡。经接种试验证明,病菌的冬孢子一担孢子不侵染竹秆和竹笋。夏孢子在5~6月产生释放,从伤口侵染当年新竹及老竹。据普查,该病已广泛分布浙江竹区,计已有1市9县24处竹林发生,寄生竹种达16种以上。它对竹林生长和出笋已带来较大的损失,已成为我省竹子上的常见病、多发病、慢性病、顽固病。笋用竹基地及产笋专业户必须对防治加以高度的重视。

Hippota dorsalis (Stal) belongs to the family of Pentatbmidae, which is a main pest occured in recent years in the bamboo foresc of the North-west part of Zhejiang Province.According to the observation, there were 5400 hectares of bamboo stands damaged by it in 1987 in Anji County.This insect had one generation per year.98% of them lived through winter by fourinstar nymph, and in the first and middle ten days of April of next year when the mean temperature of day was 10—25℃ and the relative humidity was over...

Hippota dorsalis (Stal) belongs to the family of Pentatbmidae, which is a main pest occured in recent years in the bamboo foresc of the North-west part of Zhejiang Province.According to the observation, there were 5400 hectares of bamboo stands damaged by it in 1987 in Anji County.This insect had one generation per year.98% of them lived through winter by fourinstar nymph, and in the first and middle ten days of April of next year when the mean temperature of day was 10—25℃ and the relative humidity was over 50%, its nymph climed up to the bamboo culms and got food, the quantity of which was increasing while the air temperature was rising and the relative humidity going down.The eclosion of the adults was from the end of May to the beginning of June.After taking supplemental nutrients for 22 days, the adults mated each other and then the female oviposited 30 days later.When the atmospheric temperature reached 27℃ for 3—7 days, the eggs hatched.The nymph had five instars and the first instar nymph did not take food.In Oct.or Nov.when the mean day temperature was below 10℃, the nymph prepared to live on through the winter.It could be cbntroled by making isolating poisonous ring on culms, or spraying 2.5% Decis emulsion of 20 ml per 0.0667ha.on ground, or injecting 50% Methamidophos of 1—2 ml into each bamboo

竹卵圆蝽Hippota dorsalis(Stal)属半翅目、蝽科。是近年来在浙江西北部竹林中暴发的一种重要害虫。据安吉县1987年调查,受害竹林面积已达8.1万亩。该虫在浙江安吉为一年一代,于11月以4龄若虫在地表落叶层下越冬,翌年4月上中旬开始取食为害,若虫5龄,除越冬外,若虫常年在竹上为害。用黄油、机油、溴氰菊酯混合剂在竹秆基涂环可阻止若虫上竹,在秆基注射50%甲胺磷乳剂,虫口减退率达90%以上。
