고추$\cdot$참깨등 경제작물에 발생하는 병해는 수십여종이 있으나 그중 국내에서 흔히 발생하며 피해가 큰 병해는 곰팡이병으로 노균병, 잿빛곰팡이병, 탄저병, 균핵병, 시들음병, 역병 등 6종, 세균병으로는 무름병, 풋마름병, 세균성점무늬병등 3종, 그리고 바이러스에 의한 병을 들수 있다. 이 병해들은 그 종류별로 병징, 병발생 양상, 전염방법 등에 특징이 있기 때문에 기생하고 있는 작물이 다를지라도 병의 구별이 가능하고 동일종류에서는 병의 방제방법도 비슷하다. 최근 문제되고 있는 병해를 중심으로 진단법과 방제법을 알아본다.

우리 식생활에 없어서는 안되는 양념 채소인 고추는 이른 봄부터 늦가을까지 재배기간이 긴 작물로서 특히 고온다습한 장마철에 방제하기가 어려운 병충해의 발생이 심한 것으로 장마철의 주요 병해충을 보면 돌림병(疫病)을 비롯해서 검썩음병과 바이라스, 반점세균병 그리고 담배나방을 들 수 있다. 이들 중 가장 무서운 피해를 주는 것은 연작포장에서 심하게 발생되는 역병과 고온다습한 공기를 타고 급격히 전염되는 탄저병 그리고 반점세균병과 진딧물이 매개하는 바이러스 즉, 오갈병과 연중 3$\~$4회 발생하여 피해를 주는 담배나방이 있다.

''87년하면 누구나 여름에 비가 너무 많이 왔다는 것을 잊을 수 없을 것이다. 농작물의 병해는 이러한 기상환경 변화에 따라 발생양상이 크게 달라질 수 있다. ''87년도에 발생한 채소 병해중에서 특히 피해가 많은 병해를 중심으로 노지에서는 고추 병해, 비닐하우스에 재배하는 채소 중에서는 오이, 수박, 상치, 셀러리의 병해에 대하여 살펴보기로 한다.

1. 고추 무농약재배 비가림 시설재배 효과 무농약 고추 노지 터널재배와 비가림 재배의 수량성을 검토하고, 관행 비가림 시설에 측고와 동고를 높이고 가로대를 보강하여 최소한의 투입으로 작물재배 환경을 개선으로 농작업에 편리성을 도모하고자 시험을 수행한 결과 비가림 시설재배가 노지 터널재배에 비하여 생육이 양호하고. 수량이 2배정도 많았다. 노지재배 고추는 강우로 인하여 탄저병이 40% 정도 발생되었으나, 비가림 시설재배는 탄저병과 역병이 전혀 발생되지 않았다. 2. 고추 비가림 시설 환경 개선 효과 구명 비가림 시설의 측과와 동고를 높이는 간단한 환경개선으로 여름철은 시설내 온도가 관행 비가림 시설보다 낮아지는 효과가 있었다. 또한 비가림 시설환경 개선에 의해서 "녹광" 풋고추의 생육은 증가되었으며, 홍고추 "조양" 품종도 같은 경향이었다. 고추의 수량은 풋고추 "녹광" 품종이 홍고추 "조양" 품종보다 수확량이 현저하게 많았고 처리간에는 비가림 시설의 환경을 개선한 시설이 관행 비가림 시설에 비하여 증수되었다. 그리고 비닐온실의 측고를 높인 결과 비닐 온실 내 측면으로 사람의 통행이 자유로워 작업환경 도도 개선되었다.

This study was to investigate beneficial effects of microbial mixture on red pepper which was capable of promoting plant growth by solubilizing insoluble phosphate as well as protecting plants from pathogenic attack. Saccharomyces sp. L13 was isolated for phosphate solubilizing activity on aluminium phosphate, tricalcium phosphate, calcium hydrophosphate, and magnesium hydrophosphate. On the other hand, Bacillus sp. L32 was isolated for antagonistic activity against Phytophthora capsisi and Colletotrichum gloeosporioides, causing Phytophthora blight and Anthracnose disease in pepper, respectively. The strain L32 exhibited antagonistic activities both under dual culture assays and detached leaves assays. The each strain under the condition of mixed cultivation exhibited the same growth rates as one under pure cultivation. In greenhouse study, the mixed culture showed the both effect of plant growth promotion and reduction of disease symptom development against P. capsisi and C. gloeosporioides providing a potential as effective microbial agent for plant husbandry.

The siderophore ($siderophore_{AH18}$) of Bacillus subtilis AR18 was determined to be one of catechol type and purified by using Amberlite XAD-2, Sephadex LR-20 chromatography, and reversed-phase RPLC. The $Siderophore_{AH18}$ was identified bacillibactin with its structure by GC-MS, $^1H$-NMR, and $^{13}C$-NMR. $Siderophore_{AH18}$ (bacillibactin) had been confirmed its molecular weight of 883 and chemical structure of $(2,3-dihydroxybenzoate-glycine-threonine)_3$. Purified $siderophore_{AH18}$ showed strong biocontrol ability towards the spore of Phytophthora capsici on PDA and able to effectively suppress (55%) P. capsici causing red-pepper blight in the pot in vivo test.

The biocontrol agent Serratia plymuthica A21-4 was selected and proved as an excellent inhibitor of Phytophthora blight of pepper through in vitro and in vivo experiments in previous studies. To enhance the colonizing density of S. plymuthica A21-4 on plant root and rhizosphere soil, some soil conditions might effect on the colonization of the bacteria were examined. The results obtained from the study indicated that the soils containing more sand were favorable to root colonization of S. plymuthica A21-4. Organic amendment such as 3% maize straw(w/w) was helpful to colonize the bacteria in root and soil. The soil temperature about $20^{\circ}C$, water content around 40%, and soil pH near to neutral or slightly acidic, were optimum condition for the colonization of S. plymuthica A21-4 in the rhizosphere soil and roots of pepper. In addition, existence of indigenous biotic entities was beneficial to the colonization of S. plymuthica A21-4.

Effect of Metalaxyl-Mz and Aliette-F to Phytophthora capsici was studied in vitro and in vivo. Metalaxyl-Mz was more inhibitory than Aliette-F on Mycelial growth. Although Aliette-F had more inhibitory effect on zoosporangial formation, there was no big difference among the other concentrations of the two fungicides. A higher inhibitory trend of zoosporangial formation, however, was resulted by the chemical when compared to the control. The extract obtained from the red pepper treated with Metalaxyl-Mz showed a good inhibitory effect on mycelial growth, and there was not so big difference between 400 and 600 times concentrations. The 1000 times concentration was less inhibitory than the above two concentration levels. Although there no distinct difference the two chemicals, Aliette-F and Metalaxyl-Mz, however, preventive effect was higher than curative effect under the green house tests.

Effect of suppression for zoosporangial germination and mycelial growth of Phyto­phthora capsici causing red pepper fruit rot, was carried out in vitro test by using $NH_4OH$ and $KNO_2$, as ammonium/ammonia, nitrite/nitrous acid and $CaCl_2$, as calcium ion. Results of in vitro tests with $NH_4OH$, $KNO_2$, and $CaCl_2$, mol solutions demonstrated that zoosporangial germination of P. capsici was inhibited about 15 to 50% compared with control, according to $NH_3$, HNO as nonionized form and $Ca^{+2}$ ions. Ammonia concentration$(NH_3)$ was proportionally increased by high pH level and mol concentration, whereas low pH and high mol concentration showed rather higher concentration of $HNO_2$. Ammonia were more toxic at pH 8 than at pH 7 under the same concentration, while nitrous acid$(HNO_2)$ was more toxic than at pH 8. The zoosporangial germination inhibition in the ammonium/ammonia and nitrite/nitrous acid solutions demonstrated that $NN_3$, and $HNO_2$, were primarily responsible for the inhibition at lower concentration and mor" toxic by increasing concentration. $Ca^{+2}$ ions showed that zoosporangial germination was inhibitory by high pH level and increasing mol concentration in comparison with buffer conlrol. pH levels affected to mycelial growth of the fungus, and especially, high pH caused rather retardation of mycelial growth. There was no definite inhibitory response of mycelial growth at various degree concentrations of the toxicant solutions.
