배 과원 문제해충의 하나인 꼬마배나무이(Cacopsylla pyricola)의 월동성충이 낳은 알에 대해 10, 13, 18, 22, 25℃에서 부화율을 조사하여 온도와 발육률에 대한 선형모형으로 Y=0.00319X + 0.00615((R2=0.809899)(Y=temp., X=dev. rate))로 도출하였고, 알에 대한 발육영점온도는 약 –1.94로 추정되었다. 포장에서 월동성충이 낳은 알이 50%를 초과하여 부화하는 시기와 2월 1일부터 일일 최고기온 6℃ 이상의 온도를 누적한 결과, 2008, 2009, 2011년에 각각 429.7, 417.6, 424.3일도였으며, 이는 만개기를 기준으로 만개 3~7일전이다. 한편 아바멕틴 유제, 석회유황합제, 기계유유제, 및 유기농업자재 13종은 월동성충이 낳은 알에 대한 살란 효과는 없는 것으로 생각되고, 배 생육기인 2012년 5월 21일, 6월 5일 2회 살포시 방제가 90% 이상을 보인 유기농업자재는 D사의 Azadiractin A+B, Nimbin, Salanin, Meliantriol, Vepol 등 혼합물 등 4종이었다.

This study was conducted to select and develop effect of eco-friendly organic materials for the eco-friendly prevention of Anthracnose occurred in the ginseng. Anthracnose on ginseng is occurred by Colletotrichum gloeosporioides and the crop damage is severe especially from July to August after rainy season. The test results showed that control effect by test products materials on the three years ginseng and four years ginseng field was lower in eco-friendly organic materials than that of chemical pesticide. However, the control effect of bordeaux mixture was higher with 71.3% and 73.8% levels than those of mineral matter, microbial agent, and developed plants extract mixtures (Eugenol, Curcumin, Wood vinegar, etc). On the other hand, three types of developed plants extract mixtures (3 types) showed control effect in a range of from 58.1% to 63.6% against Anthracnose which was higher as compared with plant extract alone and sodium silicate regardless of ages of ginseng. The results of this study would attribute in verifying the control effect of eco-friendly materials against Anthracnose for ginseng through investigating antimicrobial compounds contained in the plants body. Also, it would be used as control method against Anthracnose occurred in ginseng by judging the right control time through monitoring occurrence of disease.
