Guideline for the efficacy evaluation of herbicides

The biological evaluation of a herbicide involves a programme of trials for assessment of efficacy in weed control and of selectivity to the crop. Trials may be used for efficacy evaluation or selectivity evaluation according to weed occurrence, provided the conditions specified in the guideline are satisfied.
This guideline gives detailed instructions for the conduct of single trials and general recommendations for the whole evaluation programme which may include other trials (practical use trials, succeeding crop trials, varietal sensitivity trials–Appendix I).     

Der gezielte Einsatz von reduzierten Aufwandmengen herbizider Tankmischungen in Mais – ein Beitrag zur Umsetzung des integrierten Pflanzenschutzes in der landwirtschaftlichen Praxis

The competitive ability of maize is low in its early growth stages and because of this weed control is essential. Agricultural practice is dominated by chemical weed control. The trials indicated that some herbicide mixtures used at 75% of the permitted dose have herbicidal potential. In trials in the states Brandenburg, Sachsen, Sachsen-Anhalt and Thüringen, four herbicide mixtures were tested in the years 2004 to 2006.The practiced 75% of permitted dose and 50% of permitted doses were tested for their herbicidal potential. The weed species react differently to reduced herbicide doses. 50% of the 26 recorded weed species showed no drop in herbicide treatment efficacy at a reduced dose compared to the recommended dose. A drop in efficacy of between 1 and 5% was recorded after use of reduced herbicide rates in 25% of the other recorded weed species. 15?% of all recorded weed species showed a drop of efficacy of between 5 to 10%. Only 10% of recorded weed species reacted with an efficacy drop of more than 10?% between recommended and reduced doses. The tested herbicide mixtures had a different herbicidal potential for specific weed species. The herbicide treatment in maize is carried out after emergence of the weed species. It is therefore possible to choose the most suitable herbicide mixture at the 50% dose rate with the smallest drop of efficacy to target the specific species. In this way only slightly more weeds survive at a higher density compared with the recommended dose rate. The selection pressure is hardly higher. The knowledge of the herbicidal potential of mixtures could be used in agricultural practice. In this way the input of active ingredient/area can be reduced by the approximate efficacy of herbicide treatments. The tested herbicide mixtures are only an example of how, by the knowledge of efficacy reserves of herbicide in relation to the weeds present, the applied dose can be better adapted to the treatment frequency index.     

氰氟草酯使用技术对双穗雀稗防除效果的影响

为明确氰氟草酯防除双穗雀稗的最佳使用技术,采用室内试验和田间试验相结合的方法,明确氰氟草酯在不同施药情况下对双穗雀稗的防除效果。室内试验结果表明,氰氟草酯对双穗雀稗具有较好的防除效果,LD50为有效剂量26.15g/hm2;田间试验结果表明,在全株受药情况下,施用10%氰氟草酯乳油有效剂量90~270g/hm2对苗期至营养生长盛期双穗雀稗均具有较好的防除效果,防除效果接近100%。室内和田间不均匀施药试验结果表明,双穗雀稗喷施氰氟草酯部分防除效果较理想,未施药部分防除效果随着施药部分剂量的增加而增加。总体来讲,施药不均匀是导致防除效果波动的一个主要原因。在施药均匀、全株施药的情况下,10%氰氟草酯乳油有效剂量90g/hm2对双穗雀稗具有很好的防除效果,在不能保证均匀全株受药的情况下,10%氰氟草酯乳油防除双穗雀稗的使用剂量应该提高到有效剂量270g/hm2。     

农药田间药效试验工作的经验及做法

农药田间药效试验有别于一般防治示范或简单的效果观察。它是农药在进入市场之前,国家为保证农药对有害生物的防治效果和对作物及环境的安全性而开展的一项重要工作。农药田间药效试验需要对农药产品防治效果、负面效应以及环境影响作出客观、公正的综合评价,为农药生产企业办理农药登记提供资料,为农药推广应用提供科学依据。为保证农药田间药效试验的准确性和对试验药剂进行客观合理的分析、评价,笔者通过多年的实践经历,总结了做好农药田间药效试验经验以及具体做法。     

A Rapid Method for Screening Insecticides in the Laboratory

An efficient method for rapidly mass-screening insecticides for use against sap-feeding virus vectors is presented with a case study of 30 chemicals. The method permits large numbers of insecticides to be tested simultaneously and relatively inexpensively in a sequence of laboratory bioassays. The sequence is designed to find the most effective pesticide at the lowest concentration giving control without phytotoxicity. The system was derived to test candidate insecticides to control tomato yellow leaf curl virus vectored by the tobacco whitefly, Bemisia tabaci Gennad., the most serious pest of greenhouse and field tomatoes in the Middle East. Although the insecticides were all more efficacious in the laboratory than in the field, bioassay results were highly correlated with results from field trials, giving high confidence that the screening process selected only the most efficacious insecticides. Most of the insecticides accepted by the screening process have since been adopted by vegetable growers in Israel. The method is not intended to eliminate field efficacy trials, but to reduce the number of trials and treatments that need to be performed, thereby reducing costs. The method provides for the optimization of application rates which will contribute to the expected life of insecticides before resistance develops, and will also help to reduce environmental contamination. In addition, the method is suitable for estimating relative efficacy for pesticide benefits assessments, a required part of the (re-)registration process for pesticides in some countries. Although developed for screening insecticides against virus-transmitting sap-feeding insects, the method could be modified to assess the efficacy of insecticides in controlling other insect pests.

Selectivity of foramsulfuron + thiencarbazone‐methyl and classic herbicides in sensitive and non‐sensitive sugar beet genotypes

A new herbicide for sugar beet cultivation using the ALS‐inhibiting active ingredients foramsulfuron and thiencarbazone‐methyl is under approval in the EU member states. Sugar beet genotypes that are non‐sensitive to this herbicide are currently under development. Selectivity of the ALS‐inhibiting herbicide and yield response of the non‐sensitive genotypes might be relevant to meet the requirements for variety registration. To evaluate these issues, six field trials were conducted in Germany in 2013 and 2014. Classic herbicides and the ALS‐inhibitor herbicide were applied in dosages of up to fourfold the authorised (or applied for) application rates. The ALS‐inhibitor herbicide did not cause any significant phytotoxicity and had no effect on leaf area index at a single, double or fourfold dosage. By contrast, classic herbicides had significant negative effects at the single dosage. At fourfold dosage, they caused 41% phytotoxicity and reduced leaf area index by 35%. The relative yield difference between ALS‐inhibitor and classic herbicide treatments was 8.6% and 17.4% of white sugar yield at double and fourfold dosage respectively. The ALS‐inhibitor herbicide thus showed higher selectivity than the classic herbicides. In the registration process, the resulting yield advantage could balance a possible yield penalty of non‐sensitive genotypes. The introduction of a new system for weed control could improve application flexibility and control of troublesome weeds in sugar beet.
