Izihlahla zama-apula zingena kancane kancane esikhathini sokuqhakaza. Ngemuva kwesikhathi sokuqhakaza, njengoba izinga lokushisa likhuphuka ngokushesha, izinambuzane ezidla amaqabunga, izinambuzane zamagatsha nezinambuzane zezithelo zonke zingena ekuthuthukisweni okusheshayo kanye nesigaba sokuzala, futhi imiphakathi yezinambuzane ezihlukahlukene izokhula ngokushesha.
Cishe ezinsukwini eziyi-10 ngemuva kokuwa kwembali yisikhathi sesibili esibalulekile sokulawula izinambuzane zesihlahla sama-apula. Nakisisa ukuvela kwezinambuzane ezinkulu. Uma inani labantu selifinyelele inkomba yokulawula, izinyathelo zokuvimbela nokulawula kufanele zithathwe ngesikhathi.
Ngaphambi nangemva kokuwa kwembali, bheka ikakhulukazi isimo somonakalo wamaqabunga, amahlumela amasha, izithelo ezincane namagatsha, ugxile ezibungwini zesicabucabu esibomvu, amabhu e-leaf roller, ama-aphid aphuzi a-apula, izintwala ze-apula zoboya, izimbungulu eziluhlaza, izikelemu zikakotini namabhungane ama-longhorn, njll. ., futhi uhlole ukuthi azikho yini izimpawu emakhasini angaphakathi. Kukhona ama-spider mite abomvu, ama-aphid emahlumela amasha, izimbungulu eziluhlaza phezu kwamahlumela amasha, futhi uhlole ukuthi zikhona yini izibungu ze-bollworm emaqabunga amancane nezithelo ezincane.
Ngezithombo nezithombo, gxila ekuphenyeni ukuthi zikhona yini izibungu zenundu eziqothukela phezulu eziqongweni zamagatsha namaqabunga egatsha, ukuthi zikhona yini izintwala ezimhlophe (ukulimala kwama-aphid angama-apula) ezibazini zamagatsha kanye nokusikeka kwamasaha, nokuthi zikhona yini inqwaba yezibungu ze-leaf roller moth eziqwini naphansi. Ubulongwe obusha obufana ne-sawdust (ingozi yebhungane enezimpondo ezinde). Uma inani lezinambuzane lilikhulu, khetha ukufafaza kwesibulala-zinambuzane okunezimpawu ngokohlobo lwezinambuzane.
Kuyaqapheleka ukuthi izithelo ezisencane zizwela izibulala-zinambuzane futhi zithambekele ku-phytotoxicity. Ukufafazwa kwamalungiselelo e-concentrate emulsifiable kanye nezibulala-zinambuzane ezisezingeni eliphansi kufanele kugwenywe ngalesi sikhathi. Mayelana nokukhiqizwa, izinkomba ezithile zokuvimbela nokulawula kanye nezinyathelo ngesikhathi sokusebenza kwangempela zimi kanje:
Lapho inani lezibungu zesicabucabu litholakala lifinyelela ku-2 iqabunga ngalinye ngesikhathi sokugada engadini, ama-acaricides afana ne-etoxazole noma i-spirodiclofen angafuthwa ukuze alawuleke.
Uma izinga le-aphid lidlula ama-60%, izibulala-zinambuzane ezifana ne-imidacloprid, i-Lambda-cyhalothrin noma i-chlorpyrifos zingafafazwa ukuze kunqandwe izintwala kanye nezimbungulu ezinuka kabi eziluhlaza, izintwala ze-apula ezinoboya kanye nezinambuzane zesikali. Phakathi kwazo, ukuze kuvinjwe futhi kulawuleke ama-aphid woolly aphid, lapho kuvela amabala engadini, angasulwa ngesandla noma asulwe. Uma kwenzeka ngokuvamile, ngaphezu kokufafaza amakhemikhali ashiwo ngenhla emagatsheni ensimu yonke, izimpande kufanele ziniselwe izikhathi ezingu-1000 ze-10% imidacloprid powder wettable.
Uma kunezikelemu zikakotini eziningi engadini yezithelo, ungafafaza izibulala-zinambuzane ezifana nosawoti we-emamectin kanye ne-Lambda-cyhalothrin, ezingaphinda zilawule izinambuzane ze-lepidopteran ezifana nezikelemu zenhliziyo kanye namarola amaqabunga.
Uma uthola imbobo entsha yokuhlanza esiqwini sesihlahla, sebenzisa isirinji ngokushesha ukujova u-1 kuya ku-2 ml wesisombululo esiphindwe izikhathi ezingama-50 kuya kweziyi-100 se-chlorpyrifos noma i-cypermethrin emgodini wokuzikhulula, bese uvala imbobo ngenhlabathi. Qaphela ukuthi ungajovi umuthi wokuqala ukuze uvimbele ukugxila ekubeni phezulu kakhulu. Okuphezulu futhi kubangele i-phytotoxicity.
