技术背景 technical background
随着化学农药的广泛应用，有害生物抗性、农药残留及环境污染等问题日益突出。开发低毒、低残留、对环境影响小的“环境友好”或“生物合理性农药”成为大势所趋，是当前有害生物防治的研究热点。With the wide application of chemical pesticides, problems such as pest resistance, pesticide residues and environmental pollution have become increasingly prominent. The development of "environmentally friendly" or "biologically rational pesticides" with low toxicity, low residue, and little impact on the environment has become a general trend and is a research hotspot in pest control.
植物源农药来源于自然，能在自然界降解，通常不会污染环境及农产品。在环境和人体中积累毒性的可能性小，对人畜相对安全，对害虫天敌伤害小，具有低毒、低残留的特点，能够保持农产品的高品质。Botanical pesticides are derived from nature, can be degraded in nature, and usually do not pollute the environment and agricultural products. The possibility of accumulating toxicity in the environment and the human body is small, relatively safe for humans and animals, and less harmful to natural enemies of pests. It has the characteristics of low toxicity and low residue, and can maintain the high quality of agricultural products.
植物源杀菌剂是指用具有杀菌、抑菌活性的植物的某些部位或提取其有效成分，以及分离纯化的单体物质加工而成的，用于防治植物病害的药剂。由于植物源杀菌剂通常发挥药效较慢，有效成分容易分解，在实际应用中受到一定的制约。Botanical fungicides refer to agents that are processed from certain parts of plants with bactericidal and bacteriostatic activities or extracting their active ingredients, as well as isolated and purified monomer substances, and are used to prevent and control plant diseases. Since botanical fungicides usually exert their medicinal effects slowly and the active ingredients are easy to decompose, they are subject to certain restrictions in practical application.
茶树油(Tea Tree Oil)是桃金娘科(Myrtaceae)白千层属(Melaleucal.)植物互叶白千层的新鲜枝叶经水蒸汽蒸馏而得无色至淡黄色的精油。茶树油具有较强的杀菌作用，能有效地抑制多种致病细菌与真菌，广泛应用于日用品、香料、食品、医药等行业。Tea Tree Oil is a colorless to light yellow essential oil obtained by steam distillation of fresh branches and leaves of Melaleuca alternifolia in the family Myrtaceae (Melaleucal.). Tea tree oil has a strong bactericidal effect, can effectively inhibit a variety of pathogenic bacteria and fungi, and is widely used in daily necessities, spices, food, medicine and other industries.

实施例5：含茶树油复配杀菌剂防治蔬菜病害田间实验Example 5: Field experiment of compound fungicide containing tea tree oil to control vegetable diseases
利用实施例2和3所制备的含茶树油杀菌剂复配制剂，进行田间药效试验，并且以目前常用防治灰霉病的50%异菌脲悬浮剂作为对照药剂，以清水为空白对照。试验步骤为：将本发明所提供的含茶树油的杀菌剂复配制剂水乳剂用水分别稀释200倍后，用于防治莴苣灰霉病。将现有技术中的50%异菌脲悬浮剂，用水稀释2000倍后，用于防治防治莴苣灰霉病，试验结果如表6所示。Using the tea tree oil-containing fungicide compound preparation prepared in Examples 2 and 3, a field efficacy test was carried out, and the 50% iprodione suspension commonly used to prevent gray mold was used as a control agent, and clear water was used as a blank control. The test procedure is as follows: after diluting the tea tree oil-containing fungicide compound water emulsion provided by the present invention 200 times with water, it is used for preventing and treating Botrytis cinerea of lettuce. The 50% iprodione suspension concentrate in the prior art was diluted 2000 times with water to prevent and control lettuce botrytis. The test results are shown in Table 6.
从表6可以看出，稀释之后，实施例2和3所提供的不同含量的含茶树油复配制剂与常用药剂50%异菌脲悬浮剂试验结果表明，在施药后7天的防效都比常用药剂效果好。施后后14天，实例3的防效是常用药剂的7.33倍。莴苣试验田施药2次后调查3次，各处理区莴苣的叶形、叶色、茎杆均无显著差异，这说供试药剂对莴苣是安全的。含茶树油杀菌剂复配制剂对莴苣灰霉病防治效果较好，可以减少化学农药用量，减轻农药对环境的压力。As can be seen from Table 6, after dilution, the test results of the compound preparation containing tea tree oil and the commonly used medicament 50% iprodione suspension of different contents provided by Examples 2 and 3 show that the control effect in 7 days after application All are better than commonly used drugs. 14 days after application, the control effect of Example 3 was 7.33 times that of commonly used agents. The lettuce test field was surveyed three times after spraying twice, and there was no significant difference in the leaf shape, leaf color, and stem of lettuce in each treatment area, which means that the test agent is safe for lettuce. The compound preparation of fungicide containing tea tree oil has better control effect on lettuce botrytis, which can reduce the amount of chemical pesticides and reduce the pressure of pesticides on the environment.
