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...

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,研究认为此种施药方式对天敌有显著的保护作用,而常规的喷雾、喷粉...

本文汇集了1974—1979年以来,有机磷农药(乐果、敌敌畏和乙酰甲胺磷)在蔬菜上的41个残留降解动态田间试验区中,近千份各类蔬菜样品残留量的实测数据,并对其进行数理统计分析,结果表明,这些有机磷农药在蔬菜上的残留降解规律近似于单分子一级反应,由此可求得残留半衰期。不同条件下降解速率各不相同。本文进一步对影响残留降解的环境因子作了论述,并提出了这些农药在各类蔬菜上安全合理使用的指标。

The field tests indicated that: The lowest effective dosage of the gra-nulosis virus from Pieris brassicae ( PbGV ) in the control of the small white butterfly, Artogeia rapae was in a range of 2.3 × 1010- 3.4 × 1010 GIB/mu. the GV should be sprayed in the peak period of the eggs and the low instar larvae. la spring and summer, it should be used when the hatching rate reached to about 20%. The control effects would not be negatively affected if the GV was mixed with dimethoate, omethoate and acephate just before the spraying, or it was raining in the test period, and it could be improved when the GV was sprayed in thinner droplets. In an exemplary control on an aera of 135.8mu, the number of the pest was reduced more than 90% for-each plot in 7 days after the spraying.

田同试验结果表明:大菜粉蝶颗粒体病毒(PbGV)防治甘蓝地上菜粉蝶幼虫的最低有效剂量在2.3×10~(10)~3.4×10~(10)颗粒体/亩之间;病毒的喷布应在寄主卵与低龄幼虫的高峰期进行,春夏季以在田间寄主卵孵化率近20%时使用为宜。喷布的雾滴细,可以提高防治效果。病毒与乐果、氧化乐果、乙酰甲胺磷等农药临时混用。不降低防治效果,降雨对病毒防治效果的影响不明显。在135.8亩的肪治示范试验中,菜粉蝶的虫口减退率均在90%以上,效果好且稳定。
