Description

防治柑橘类果树黄龙病的水乳剂及制备方法、使用方法 技术领域
本发明涉及一种防治柑橘类果树黄龙病的水乳剂及制备方法、使用方法。
背景技术
柑橘类果树“黄龙病”是世界柑橘生产上的毁灭性病害之一，由寄生于果树韧皮部内的类革兰氏阴性细菌(属韧皮杆菌)引起，苗木和幼龄树发病后1-2年内枯死，成年树发病后在3-5年内丧失结果能力。
柑橘类果树“黄龙病”广泛分布于世界近50个国家和地区，随着气候变暖，黄龙病的媒介昆虫分布区域逐渐扩大，同时世界资源交流逐渐频繁，致使黄龙病危害日趋严重。此病的发生将导致大面积产量降低、品质变劣甚至死亡，给柑橘经济带来巨大损失，严重影响柑橘产业健康发展。
得了黄龙病的柑橘全株系统性病害,根、树干、枝、叶、花、果都有病原,特别是根部,药剂很难达到,现在尚未找到好的给药方法和途径,也没有研制出特效的农药。当前防治方法主要有严格检疫制度，杜绝病苗人为传播，培育无病苗木，微生物防治，防治病原传播媒介——柑橘木虱等方法。然而这些方法的使用过程均有自身限制因素，均出现防治的漏洞，以至于每年在不同区域均大面积发生柑橘黄龙病害。
发明内容
本发明所要解决的技术问题在于提供一种有效防治柑橘类果树黄龙病的水乳剂。
本发明提供一种防治柑橘类果树黄龙病的水乳剂，按重量比由以下组分组成：十二醇100-300份、十六醇2-150份、杀菌杀虫剂1-100份、植物营养剂5-150份、乳化剂5-10份、助乳化剂4-6份、增稠剂40份、水500-800份。

样品A为实施例1制备的防治柑橘类果树黄龙病的水乳剂
样品B为实施例2制备的防治柑橘类果树黄龙病的水乳剂
样品C为实施例3制备的防治柑橘类果树黄龙病的水乳剂
样品D为实施例4制备的防治柑橘类果树黄龙病的水乳剂
样品E为阿维·吡虫啉(厂家：上海农乐生物制品股份有限公司(登记号：PD20141229))
作物：新会茶枝柑
地点：广东省江门市新会区双水镇泮李村
方法：在果场选取同一区域各选取50棵茶枝柑果树，按实验方案要求对果树分别进行淋根、植株喷施，间隔15天处理一次。
表1防治柑橘类果树黄龙病的实验方案

1、现场观察防治黄龙病效果，包括防治黄龙病扩散效果(柑橘木虱防治效果)和黄龙病病树的治疗效果结果如下：

柑橘木虱防治效果的计算公式为：
Figure PCTCN2020089891-appb-000004
PT——防治效果，单位为百分率(％)

PT 1——药剂处理区药后虫数，单位为头；
CK 0——空白对照区施药前活虫数，单位为头；
CK 1——空白对照区施药后活虫数，单位为头。
从表2中可以看出，使用本发明的防治柑橘类果树黄龙病的水乳剂对果树植株喷施，各个实验组对柑橘木虱都有明显的防治效果，可有效切断黄龙病的传播途径，减少黄龙病扩散，实验组在柑橘木虱的防治效果明显优于使用传统农药的对照组；从对黄龙病病树处理结果看，对果树淋根、植株喷施(单独或同时进行)都可治疗新会茶枝柑的黄龙病，处理后果树恢复生机，病症慢慢消失，同时进行淋根、喷施的实验组防治效果优于单独进行喷施的实验组，也明显优于使用传统农药的对照组，其中使用不同配方进行淋根、喷施的实验组1防治效果最好。
2、在现场分别采样实验组1和对照组不同时期病树枝叶样本，用核酸分子检测方法分析样本对亚洲黄龙病韧皮杆菌的阳性反应情况(2019-2-2的样品采用定性测试，其他时间的样品为定量测试)，确定防治效果，结果如下：
表3实验组1的果树不同时期的样品病菌检测结果
Figure PCTCN2020089891-appb-000005
Figure PCTCN2020089891-appb-000006
注：判定标准：Ct值<36，果树样本对黄龙病病菌有阳性反应，数值越小病情越严重；
表4对照组的果树不同时期的样品病菌检测结果
Figure PCTCN2020089891-appb-000007
注：判定标准：Ct值<36，果树样本对黄龙病病菌有阳性反应，数值越小病情越严重；
从表3中可以看出，同时进行淋根、喷施的实验组1的果树对亚洲黄龙病杆菌的反应：随着时间的推移，旧枝叶出现阳性反应的比例不断减少，Ct值也不断增大接近或超过阈值，说明原来病树旧枝叶中的病菌慢慢减少，果树也慢慢转为正常；处理后有新生长出叶子的枝叶部分(含旧枝、新叶)检测不到病菌，说明果树从根部、树干、长出新叶的枝干已经没有病菌，果树恢复生机，已属于正常果树了。
从表4中可以看出，常规处理的对照组果树对黄龙病菌检测一直呈现阳性反应，而且 Ct值有下降趋势，说明黄龙病菌越来越多，果树病得越来越严重。
综合以上可以看出，本实施例提供的防治柑橘类果树黄龙病的水乳剂可以有效防治柑橘黄龙病，其中，使用不同配方(实验组1)同时对果树进行淋根和植株喷施是最优的方案。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
