  • 비농경지는 농산물과 임산물을 생산하는 농경지,임야등을 제외한 모든 공지를 의미하지만 잡초방제를 대상으로 보면, 택지, 공업용지와 도로, 고속도로, 철도, 학교 운동장, 공원 등이 포함되는 공공용지로 구분할 수 있다. 농경지는 국가경제가 발전될수록 계속 잠식되어 택지, 공장부지 및 공공용지로 이용됨에 따라 비농경지 면적은 점차 확대되고 있으며 따라서 비농경지에 발생된 잡초방제의 필요성은 더욱 증대되리라 예상된다. 그러나 아직 우리나라에서는 체계적으로 비농경지 잡초의 분포, 방제법 등에 관한 연구가 거의 이루어지지 않고 있으며 잡초방제의 중요성과 관심도 매우 적은 실정이다. 따라서 비농경지에서 발생되는 잡초의 종류 및 피해양상, 잡초방제의 특성과 제초제를 이용한 잡초방제법을 정리하여 보기로 한다.

  • 잡초생태학에 대한 지식이 잡초방제법 확립의 기초가 되고 있음은 두말할 나위가 없다. 잡초의 생존과 번무에 대한 특성을 명확하게 알지 못하고서 효율적인 잡초의 방제 및 관리를 기대하기는 어렵다. 잡초의 전반적인 특성, 이른바 잡초생물학을 자세히 파악함으로써 이를 기초로 한 유효한 방제법의 수립이 가능하고, 그 결과 작물에 대한 잡초의 피해를 최소한으로 줄일 수 있다.

  • Weeds are one of the major constraints to crop production in organic farming systems. This paper reviews major results and techniques achieved with physical, cultural, and biological weed control and their perspectives in organic agriculture. Physical methods includes mechanical, thermal, lighting, electrocution, pneumatic, autonomous robot weeding control techniques. Cultural weed control methods includes mulching, tillage, crop rotation, cover crops and crop competition. Physical and cultural weed control techniques are especially important in organic farming crops where other weed control options are limited or not available without use of herbicides. Biological weed control includes mycoherbicides, innundative biological control, broad-spectrum biological control and allelopathy. Successful weed management in organic farming requires well managed integrated systems of mechanical control using newly developed machines, cultural control and biological control methods. Weed management decision-aid models may also needed to develop to provide greater assurance of achieving profitability and appropriate long-term weed management in organic farming in the future.

  • This paper reviews current status of weed science in Asian-Pacific regional agricultural systems based on the 24th Asian-Pacific Weed Science Society Conference. About 190 researchers from 16 countries including Korea participated in the Conference and presented 160 papers in 11 research areas. Major research topics were invasive weeds and their ecology, allelopathy, weed management in paddy field, weed management in field crops, and herbicide resistance. Because rice is a major food crop in Asian countries, weed control and herbicide resistance management in paddy field were a main object of research. Weed control in maize, soybean and wheat has also been studied continuously. To prevent the increase of problematic weeds and to overcome food crisis, the importance of weed-related researches has been raised. Therefore it is expected that various weed management systems and control of herbicide resistant weeds should be studied continuously in the future.

  • 사일리지용 옥수수 만파재배시 잡초방제를 위해서 알라유제 + 씨마네수화제외 4종의 제초제를 공시하여 6처리 난괴법 3반복으로 시험을 수행한 결과 얻어진 성적을 요약하면 다음과 같다. 1. 제초제 처리후 옥수수 출현은 처리간 차이 없이 양호하여 공시한 제초제 모두 옥수수에 약해를 미치지 않았다. 2. 제초제 처리별 잡초방제는 기존처리구인 알라유제 + 씨마네수화제 처리구보다는 파라코액제, 글라신액제, 글루포시네이트암모늄액제 및 설포세이트액제를 추가한 처리구에서 방제율 92-94%로 우수하였다.(중략)

  • This study was conducted to clarify effects of weed control methods on damages from agricultural chemicals of pear trees, growth of weeds and states of pear trees after treating pear orchards with different methods of weed controlling, density of GLU and application times. The growth and occupation rate were investigated after 10, 20 and 40 days of weeding treatment. According to a result of the first treatment conducted when weeds in the lower parts of crown in a pear orchard began to grow and grew about 20 cm, unwoven cloth covering showed the highest control value with 100% in all 14 kinds of grasses. In comparison, Stellaria aquatica and catchweed bedstraw showed 96.7% and 97.3% respectively in the 20 DAT investigate after the first treatment of GLU 540 g a.i. ha-1 and the high control value of 100% in other all kinds of grasses. According to an investigation of stalk enlargement, length of new shoot and the number of new shoot made to know differences in tree growth following treatment of the lower part of crown, to use weed killers two or three times a year or to eliminate grasses with machines have positive effects on cross growth of pear trees.
