一、防控技術

1、種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)處(chu)理(li)(li)(li)。通過種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)干熱處(chu)理(li)(li)(li)或(huo)者藥(yao)劑浸(jin)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)可(ke)有(you)(you)效降低西瓜及其砧木種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)帶毒幾率。黃(huang)瓜綠(lv)斑駁花葉(xie)病(bing)毒病(bing)可(ke)將種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)（含水(shui)量4%以(yi)(yi)下）置(zhi)于72℃恒溫(wen)下處(chu)理(li)(li)(li)72小(xiao)時(shi)，檢查發芽率后(hou)浸(jin)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)催芽或(huo)直接(jie)播種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)，在(zai)升溫(wen)和降溫(wen)時(shi)可(ke)設置(zhi)35℃、50℃兩個溫(wen)度進行緩沖處(chu)理(li)(li)(li)，每個溫(wen)度處(chu)理(li)(li)(li)24小(xiao)時(shi)，以(yi)(yi)減(jian)小(xiao)高溫(wen)對種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)發芽率的(de)(de)影響；或(huo)者用(yong)10%磷酸(suan)三鈉溶液浸(jin)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)20—30分鐘(zhong)，清(qing)水(shui)洗凈后(hou)催芽播種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)。疫情發生(sheng)高風險區可(ke)采用(yong)干熱處(chu)理(li)(li)(li)結(jie)合藥(yao)劑浸(jin)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)方(fang)法，確保病(bing)毒不帶入大(da)田生(sheng)產。預防瓜類(lei)果斑病(bing)可(ke)用(yong)1%的(de)(de)鹽酸(suan)浸(jin)漬5分鐘(zhong)，或(huo)以(yi)(yi)1%次氯(lv)酸(suan)鈣浸(jin)漬15分鐘(zhong)，或(huo)者過氧乙酸(suan)600倍液處(chu)理(li)(li)(li)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)30分鐘(zhong)（無(wu)籽瓜種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)不能用(yong)酸(suan)處(chu)理(li)(li)(li)），接(jie)著水(shui)洗、風干，都可(ke)以(yi)(yi)有(you)(you)效去除種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)攜帶的(de)(de)病(bing)菌(jun)，大(da)幅度降低田間(jian)發病(bing)率。

2、嫁接消(xiao)毒(du)。在嫁接等農事操作過(guo)程中，對手和(he)工具(ju)用10%磷酸三鈉或75%乙醇(chun)進行消(xiao)毒(du)，嫁接1次消(xiao)毒(du)1次，避免病毒(du)交叉侵染。

3、輪作(zuo)換茬。瓜類(lei)集中種植區要實行葫蘆科作(zuo)物與非葫蘆科作(zuo)物輪作(zuo)換茬。

4、加(jia)強田間管理(li)。科學肥水(shui)管理(li)，培育壯(zhuang)苗健(jian)苗，提高植(zhi)株抗(kang)病(bing)(bing)性，避免大水(shui)漫灌和氮肥過量，防(fang)止病(bing)(bing)毒傳(chuan)播。

二、工作措施

1、加(jia)強技(ji)術宣(xuan)傳與指(zhi)導(dao)。各(ge)鎮(zhen)（街道）要加(jia)大對西瓜(gua)(gua)等種(zhong)(zhong)(zhong)子(zi)經銷(xiao)商(shang)、種(zhong)(zhong)(zhong)苗繁育大戶和種(zhong)(zhong)(zhong)植戶的宣(xuan)傳，及(ji)時告知黃瓜(gua)(gua)綠斑駁花葉病毒病的危害和關鍵(jian)防控(kong)技(ji)術，提(ti)高種(zhong)(zhong)(zhong)子(zi)檢疫(yi)帶證率(lv)及(ji)防控(kong)技(ji)術到位率(lv)。要摸清(qing)本鎮(zhen)（街道）西瓜(gua)(gua)主要種(zhong)(zhong)(zhong)植基(ji)地及(ji)種(zhong)(zhong)(zhong)植戶的基(ji)本情(qing)況(kuang)，建(jian)立定期聯系及(ji)回訪制度，主動上門提(ti)供(gong)技(ji)術指(zhi)導(dao)與服(fu)務。對于本轄區內外來(lai)的西瓜(gua)(gua)承包種(zhong)(zhong)(zhong)植大戶，要做到宣(xuan)傳無(wu)死角，技(ji)術指(zhi)導(dao)全(quan)覆蓋。

2、開(kai)展種(zhong)(zhong)子(zi)(zi)(zi)（苗(miao)）檢驗(yan)檢疫(yi)(yi)。目前，我區(qu)(qu)西(xi)瓜用種(zhong)(zhong)以外地調(diao)入為主，把好(hao)種(zhong)(zhong)子(zi)(zi)(zi)檢疫(yi)(yi)關(guan)，可防范帶毒種(zhong)(zhong)子(zi)(zi)(zi)進(jin)(jin)(jin)入大田(tian)生產(chan)。農業部(bu)門(men)不定期(qi)對轄區(qu)(qu)內種(zhong)(zhong)子(zi)(zi)(zi)經營門(men)市及種(zhong)(zhong)植戶進(jin)(jin)(jin)行(xing)(xing)調(diao)查并記錄相關(guan)信(xin)息，查驗(yan)種(zhong)(zhong)子(zi)(zi)(zi)來(lai)源(yuan)(yuan)及受(shou)檢情況。對從發生區(qu)(qu)調(diao)入的(de)(de)種(zhong)(zhong)子(zi)(zi)(zi)進(jin)(jin)(jin)行(xing)(xing)復檢，必(bi)要(yao)時抽樣送檢，禁(jin)止銷售(shou)無證調(diao)運的(de)(de)種(zhong)(zhong)子(zi)(zi)(zi)。對種(zhong)(zhong)苗(miao)繁育基地進(jin)(jin)(jin)行(xing)(xing)重點檢查，要(yao)求種(zhong)(zhong)苗(miao)生產(chan)者提(ti)供西(xi)瓜及其砧木(mu)種(zhong)(zhong)子(zi)(zi)(zi)來(lai)源(yuan)(yuan)、數量、產(chan)地、受(shou)檢情況等(deng)信(xin)息，嚴格按照相關(guan)程序開(kai)展檢疫(yi)(yi)。

3、嚴格(ge)疫(yi)(yi)情處(chu)置(zhi)(zhi)。各鎮（街道）要在顯癥(zheng)高峰期對(dui)瓜類集中種植(zhi)(zhi)區(qu)、種苗繁育基(ji)地(di)、病害發(fa)生(sheng)區(qu)及其周邊區(qu)域進行(xing)疫(yi)(yi)情監測與調(diao)查。發(fa)現(xian)疑(yi)似染病植(zhi)(zhi)株立(li)即與區(qu)植(zhi)(zhi)保植(zhi)(zhi)檢(jian)站(zhan)聯(lian)系，以便采樣(yang)送(song)省級(ji)植(zhi)(zhi)物(wu)檢(jian)疫(yi)(yi)機(ji)構指定的(de)單(dan)位進行(xing)實驗(yan)室檢(jian)測。一旦疫(yi)(yi)情確認，及時開展(zhan)疫(yi)(yi)情處(chu)置(zhi)(zhi)，鏟除發(fa)病地(di)點的(de)染病植(zhi)(zhi)株，并對(dui)周邊葫蘆科作物(wu)種植(zhi)(zhi)田(tian)塊進行(xing)踏查，確保疫(yi)(yi)情不(bu)擴散。
