摘要
通过对江西种植的籽粒苋病虫害调查表明：苗期害虫主要有小地老虎、蝼蛄，叶部主要害虫有甜菜白带野螟、短额负蝗、中华稻蝗；茎部主要害虫有筛豆龟蝽以及花、穗主要害虫有小长蝽、短肩针缘蝽，并提出通过清理种植地及周围环境、及时刈割籽粒苋等管理措施控制、预防为主，低毒药剂为辅的防治对策；籽粒苋病害在江西偶有发生，但不严重，主要有多雨、潮湿所致的软腐病、猝倒病，缺肥、土壤贫瘠、干旱引起的茎腐病和茎枯病以及由于施未腐熟有机肥造成的青枯病，并提出加强田间水肥管理，施用腐熟有机肥等措施控制病源为主的防治对策。
A survey on
diseases and insects in Grain amaranth planted in Jiangxi Province showed, that the main
pests in seeding stage are Agrotus ypsilon Rottemburg, Cryllotalpa orientalis Yang, the main
insects on leaf are Hymenia recurvalis Fabricius, Atractomorpha sinensis Boliver, Oxya
chinensis (Thunberg), on stem are Megacopa cribriaia (Fabricius), on flower and tassel are
Nysius ericae (Schilling) and Cletus pugnator Fabrias. The preventive measures are clearing
the planting place and its environment, harvesting in time. In controlling the pest, the policy of
putting prevention first with supplement of low virulence pesticide should be carried out. A few
diseases in Grain amaranth occur in Jiangxi Province, but they are not serious. The major
diseases are Erwinia sp. and Phthium debaryanum Hesse caused by rainy weather and
damp air, Pellicularia rolfsii (Socc.)West and Diplodia amaranthi Teng caused by fertilizer
deficiency together with impoverished and dry soil and Pseudomona caused by applying
undecayed organic fertilizer. The emphasis in controlling these diseases should be put on
controlling the pathogeny. Strengthening the irrigation and fertilizing administration, applying
decayed organic fertilizer etc, are the major measures.
