With the growing need for greater operational capacity, information about the effect of application volume and spray nozzles on the quality of pesticide application are essential to obtain greater efficiency in pest management in cotton crops. This study aimed to assess the effect of the spraying volume and nozzles on the deposition of spray solution on cotton crops at the reproductive stage. The treatments of the first experiment correspond to the 55, 67, 140 and 194 L ha-1 volumes obtained by variation of the displacement speed using the XR11004 flat fan nozzle. In the second assay the treatments corresponded to the applications of MGA9004 (hollow cone), XR11004 (flat fan), AIXR11004 (air induction flat fan) and CVIA04 (air induction hollow cone) nozzles with 120 L ha-1. An artificial brilliant blue food dye (FD&C 1) was used as a tracer (2.5 g L-1) to determine the deposited volumes on the leaves of the upper, middle and lower third of cotton plants. The results showed that increase in the application volume contributed to obtain the larger deposits in the upper third of the cotton crop during its reproductive phase, especially up to 140 L ha-1, but did not exhibit a significant increase of the deposition in the middle and lower thirds of the plants. The MGA9004, XR11004 and AIXR11004 nozzles provided the largest deposits in the three plant sectors. The flat fan nozzles resulted in greater uniformity of deposits in the upper and middle thirds of the plants. |

Black rot caused by Xanthomonas campestris pv. campestris(Xcc) is one of the most important diseases affecting Brassica oleracea crops in Brazil. In the present study, 150 bacterial isolates from symptomatic leaf samples of broccoli, kale, Chinese cabbage, cauliflower, wild mustard, radish, and cabbage were identified and characterized phenotypically and genotypically. One isolate from a symptomatic tomato plant that grew spontaneously in a diseased cabbage field was also identified. Of these 151 isolates, 145 were confirmed as Xcc by multiplex PCR with Xcc and X. campestris pv. raphani(Xcr) specific primers and were pathogenic to cauliflower cv. Verona, including the isolate from tomato. The identity of six isolates that, although PCR positive for Xcc, were not pathogenic to cauliflower was determined by partial sequencing of the housekeeping rpoD gene, confirming that they were X. campestris. To investigate the ability of Xcc to infect tomato, 13 isolates were inoculated on tomato cv. Bonny Best, and six isolates, including the tomato isolate, induced chlorosis and small necrotic lesions on leaves and stems. Variability was assessed by BOX-PCR which resulted in 65 distinct haplotypes in the collection, with the largest number of haplotypes identified among broccoli isolates. In vitro copper and kasugamycin sensitivity tests showed that 143 isolates were resistant to 100 μg/mL of kasugamycin, and five isolates were resistant to 200 μg/mL of copper sulfate. From a subsample of 79 isolates, inoculated in eight differential genotypes, five races were detected (races 1, 3, 4, 6, and 9) with predominance of race 4 (54.43%, n = 43) and race 1 (32.91%, n = 26). The results provide tools for genetic breeding and the establishment of integrated black rot management programs for these important vegetables. Additionally, the newly found association between Xcc and tomato should be considered on the perspective of both brassica and tomato crop production in the country.
