    Results of five years' experiments conducted in South China indicated that root-zone application of systemic insecticides effectively controlled nearly all the potential insect pests of rice -the yellow stem borer ( Tryporyza incertulas ) , the striped stem borer (Chile suppresalis) , the pink borer ( Sesamia inferens ), the rice leaf folder ( Cnaphalocrosis medinalis ), the rice gall midge (Orseolia oryzae), the brown planthopper ( Nilaparvata lugens ) , the green leaf hopper ( Nephotetfix spp. ), the rice thrip (Baliothrips biformis) and the rice weevil (Echinocnemus squameus). Altogether 14 compounds have been evaluated for the control of various species.Dimethoate is readily absorbed by the root of rice plant and translocated to the stem and the leaf blade, more was found in the tips of young leaves. The consistently higher dimethoate residue in the young leaves may partially explain the chemical's greater efficacy in controlling the rice thrip, because the insect congregates and feeds at the tip of young leaves.Kitazine in the root-zone application can be used both as a fungicide and insecticide. At a rate of 3Kg AI/ha. , a mixture of ki-tazine and dimethoate gave a 90% control of the brown planthopper in 20 days after treatment. The residues in the rice grain through such application is expected to be well below the tolerance limit.It was found that a series of organophosphorus compounds containing the pyrimidiflyl radicle are very effective systemic insectic-icides when aplied in soil. Pyrimioxythion [O, O-diethyl-O-(2 - methoxy - 4 - metyl - pyrimdyl - 6 ) phosphoro - thionate ( N23)] was found to be the most effective systemic insecticide against the rice gall midge. It is more effective than carbofuran or diazinon with a residual action of 30 days. Generally one application is sufficient to provide effective control of the rice gall midge during the entire crop. Mixed formulations of pyrimioxythion with padan or dimehypo [S,S ( dimethylamino ) trimethylene dithiosulf uric acid ester] at a rate of 1.5 kg Al/ha. applied in the root-zone provided very effective control of rice borers, the rice gall midge and the leaf folder. This formulation appears to be of practical importance. Diazinon and pirimiphos-ethyl were also found to be effective against the rice gall midge.Acephate and tamaron are not potent as systemic insecticides but when applied in soil they provide short-term control of the yellow stem borer and the brown planthopper. They are characterized by their short residual action. Acephate when used in an admixture formulation with padan or chlordimeform, the effectiveness was found to greatly increased.According to the results of extensive trials, one application of carbofuran granules in the root-zone at a rate of 1.5 kg Al/ha. provided effective control of the rice gall midge, the yellow stem borer, the pink borer, the rice thrip, the green leafhopper and the brown planthopper. Against rice borers its residual action was found to be as long as 40 - 60 days. One application of carbofuran granules by soil incorporation in the rice seed-beds provided good control of one generation of the rice gall midge and other insect pests. The insecticide was carried with the rice seedlings to the paddy field and proved to be effective after transplanting without adverse effects on the parasite, Platygaster spp.,This method of soil application of carbofuran has been popularized among rice farmers in Kwangtung, Kiangsu and other provinces.Carbofuran, though a broad spectrum insecticide, is not very effective against the rice leaf folder. In fields wherein, in addition to the common insect pests, a heavy infestation of the rice leaf folder occurs, it is recommended to apply carbofuran in admixture, with padan or dimehypo or chlordimeform in the root-zone.Nereistoxin from a marine annelid, has served as a starting point for a group of very useful insecticides. In resent years, it has been found that padan, dimehypo and thiocyclam h)rdrogen exalate ("Evi-sect") are good systemic insecticides when applied in the root-zone f

    本文就根区施药方法的杀虫药效、杀虫作用机制、对害虫天敌的影响、农药残留量及内吸运转规律等方面进行讨论。 1975—1979年室内、田间小区和大田示范试验结果证明,根区施药(尤其是根区深层施药)具有药效高、节省用药量、残效期长、可以保护害虫天敌,帮助维持农田的生态系统平衡和减少环境污染等。 经试验过内吸杀虫剂有14种,已证明呋喃丹除对稻纵卷叶螟效果很差外,对叶蝉、飞虱、稻瘿蚊、稻蓟马、大螟、稻象(虫甲)等有特效,杀虫脒和类巴丹杀虫剂对螟虫类、稻纵卷叶螟有特效,但对稻瘿蚊则效果很差。巴丹、呋喃丹、杀虫脒性质较稳定,施于土壤里残效期可长达30-50天左右。有机磷内吸杀虫剂施于土壤里易于分解,残效期约10—25天左右。因不同药剂、不同季节和不同土壤类型而有差异。为了一次施药兼治多种主要害虫,可以采用混合剂如嘧啶氧磷混杀虫双、乐果混杀虫脒等,每亩用纯药75—100克深施,可以解决水稻生长前期30—50天的害虫为害,后期有可能靠生物天敌以达到生态平衡,尚待以后研究。 研究根区施药后对稻田蜘蛛的影响,也研究药剂对稻瘿蚊的寄生天敌黄柄黑蜂、三化螟卵寄生蜂等的影响,研究认为此种施...

    This paper gives the results of further experiments on the effectiveness of carbofuran, chlorodimeform, padan,dimehypo and thiocylam hydrogen oxalate ("Evisect") on the yellow stem borer (Scirpophaga incertulas), the rice gall midge (Orseolia oryzae), the rice thrip (Baliathrips biformis), the rice leaf folder (Cnapholocrosis medinalis) and the brown planthopper (Nilaparvata lugens). The ovicidal action of carbofuran on hte brown planthopper was also studied. Preliminary experiments on anit-feeding and systemic properties of the neem (Azadirachta indica) and other species of the family Meliaceae(including Melia toosendan, and M, azedarach) have been carried out. Results indicate the oil from the seeds of these plants possesses strong anti-feeding effect on the newly-hatched larvae of the yellow stem borer and nymphs of the brown planthopper. The oil also possesses strong repellent effect to the females of the rice gall midge.Altogether there are ten different methods of root-zone or soil application of systemic insecticides as practiced in South China.The application of systemic insecticides in admixture with nitrogenous fertilizers before transplanting seems to be a promising method for the early varieties of rice. In 1980, the techique of root-zone application of systemic insecticides has been tested and demonstrated successfully in about 100,000 mu (6600 ha.) of rice field in Hupeh, Kiangsi, Kwang-tung and other Provices of South China.Results of these experiments show that rootzone application of insecticides is less hazardous to the parasites and predators in the rice environment then when they are applied as foliar sprays, particularly to the spiders which are potent natural enemies of the brown planthopper. Hopefully the research on the method of root-zone application with throw some light in developing a new integrated pest control stragegy (IPM) for rice insect pests.
