Priming of defence genes for amplified response to secondary stress can be induced by application of the plant hormone salicylic acid or its synthetic analogue acibenzolar S-methyl. In this study, we show that treatment with acibenzolar S-methyl or pathogen infection of distal leaves induce chromatin modifications on defence gene promoters that are normally found on active genes, although the g...

Tomato spotted wilt tospovirus (TSWV) is a major economic threat to tobacco production in Georgia. Several thrips species are reported as vectors of TSWV, and three of these species are observed on Georgia tobacco, Frankliniella fusca (Hinds), F. occidentalis (Pergande), and F. bispinosa (Morgan). This study evaluated several thrips control practices for efficacy and suppressing the incidence o...

Effects of acibenzolar-s-methyl, an inducer of systemic acquired resistance in plants, on Rotylenchulus reniformis and Meloidogyne javanica in vitro and in vivo were determined. A single foliar application of acibenzolar at 50 mg/liter (5 ml of solution per plant) to 7-day-old cowpea or soybean seedlings decreased R. reniformis and M. javanica egg production by 50% 30 days after inoculation. Th...

Acibenzolar-S-methyl (BTH), bitkilerde zararlı böceklere karşı dayanıklılık veya savunmanın tetiklenmesinde ticari olarak kullanılan, yeni nesil etkili maddelerin ilk temsilcilerinden birisidir. BTH’ın böceklerin kontrolünde kullanımı hakkında yapılan çalışmalar sınırlı görünmektedir. Bu çalışmada, Dekalp mısır (Zea mays Linnaeus (Poales: Poaceae)) çeşidi, çevre dostu-bitkisel BTH içerikli bir ...

The potency of the inducers of systemic acquired resistance (SAR), acibenzolar-s-methyl, DL-alpha-amino-n-butyric acid (AABA), DL-beta-amino-n-butyric acid (BABA), gamma-amino-n-butyric acid (GABA), p-aminobenzoic acid (PABA), riboflavin, and salicylic acid (SA), in reducing reproduction of Meloidogyne javanica and Rotylenchulus reniformis in pineapple was investigated. All inducers were applie...
