Özet:

 Defoliant spraying is an important link in the mechanized cotton harvest because adequate and uniform spraying can improve defoliation quality and reduce cotton trash content. In defoliant application, application volume and spraying technology are extremely important. In this study, the effectiveness of defoliant application to cotton plant that has come to harvest with two different application volumes and three different types of nozzles with a standard field crop sprayer was determined. Application rates were 250 and 400 Lha and spraying nozzles were: 1 standard flat fan nozzle TP8006, 2 air induction nozzle AI 11002-VS and 3 dual pattern nozzle AI307003VP. A tracer BSF and defoliant were applied to mature cotton with approximately 60 open bolls and samplings for BSF deposition and spray coverage on cotton plant were done at two plant height upper layer, lower layer of plant. Before and after spraying, bolls open and leaves rate on cotton plants were calculated and filter papers were used to detect BSF deposition and water sensitive papers WSP were used to measure coverage rate of spraying methods used. Spectrofluorophotometer was used to detect the amount of tracer deposition on targets and an image process computer program was used to measure coverage rate on WSP. In analysis conclusions showed that air induction nozzle AI 11002-VS, achieved better results than the dual pattern and standard flat fan nozzles in terms of higher depositions, coverages and leaf defoliations and boll opening rates. AI nozzles operating at 250 Lha application rate provide the highest deposition and coverage rate on applications of defoliant, in addition, BSF as an indicator of the defoliant used reached on leaf beneath in merely this spray nozzle. After defoliation boll opining rate was 85- on the 7th and 12th days after spraying and falling rate of leaves was 76- at application rate of 250 Lha with air induction AI1102 nozzle.

 Yaprak dökücü ve kolza açıcı olarak kullanılan defoliant, makinalı pamuk hasadında önemli bir yere sahiptir, Eğer defoliant etkin bir şekide uygulanırsa pamuk bitkisinin yaprak dökümü oranı artar ve çıtırık kolza sayısı azaltılabilir. Yaprak dökücü uygulamada, uygulama hacmi ve püskürtme teknolojisi son derece önemlidir. Bu çalışmada, iki farklı uygulama hacmi ve üç farklı tip meme ile hasadı yaklaşan pamuk bitkisine standart tarla pülverizetörü ile defoliant uygulanarak sağlanan etkinlik belirlenmiştir. Deneyler, tarla denemeleri ve laboratuvar analizleri olmak üzere iki aşamada gerçekleştirilmiştir. Defoliant uygulama oranları 250 lha ve 400 Lha ve püskürtme memeleri 1 Standart yelpaze hüzmeli meme; TP8006, 2 Hava emişli meme AI 11002-VS ve 3 İkiz jetli meme; AI307003VP olarak seçilmiştir. Yaklaşık 60 oranında açık kozalı olgun pamuğa bir izleyici BSF ve defoliant uygulanmıştır. Pamuk bitkisi üzerinde biriken defoliantı temsilen BSF birikimi ve pamuk bitkisi üzerine püskürtülen damlaların kaplam oranını belirlemek için bitkinin iki yüksekliğinde Üst bölge, alt bölge örneklemeler yapılmıştır. Püskürtmeden önce ve sonra, pamuk bitkilerinde koza açma ve yaprak oranları hesaplanmış ve BSF birikimini tespit etmek için filtre kağıtları ve kullanılan püskürtme yöntemlerinin kaplama oranını ölçmek için suya duyarlı kağıtlar WSP kullanılmıştır. Hedefler üzerindeki izleyici birikimi miktarını saptamak için spektroflorofotometre kullanılmış ve WSPdeki kaplama oranını ölçmek için bir görüntü işleme bilgisayar programı kullanılmıştır. Analiz sonuçlarında, 250 Lha uygulama hacminde hava emişli meme AI 11002-VS, İkiz jetli meme ve Standart yelpaze hüzmeli memeden daha yüksek birikim, kaplama oranı, yaprak dökümü ve koza açılma oranları sağlamıştır, Ayrıca kullanılan yaprak dökücünün bir göstergesi olarak sadece hava emişli memede yaprak alt yüzeyinde daha fazla BSF birikimi sağlanmıştır. Çalışmada kullanılan defoliant, 250 lha uygulama hacminde hava emişli meme ile uygulamadan sonraki 7. ve 12. günlerde koza açma oranı  85 ve yaprak dökme oranı  76 olarak ölçülmüştür.
