EFFICIENCY OF THE REACTOR PRODUCT (CLOMAZONE) FOR THE CONTROL OF BUVA (CONYZA SPP.) AND CHICKWEED (ELEUSINE INDICA) IN SOYBEAN CROPS

Abstract

The objective of this work was to evaluate the efficiency of the product REATOR (Clomazone) for the control of BUVA (Conyza Spp.) and crowfoot grass (Eleusine indica) in the soybean crop, in addition to recording possible phytotoxicity effects of the treatments for this crop. The experiment was conducted at the University Research Center, latitude S:23º19'11.03", longitude W:51º9'58.323", altitude 480m, in the municipality of Londrina, Paraná.  The cultivar used was HO iguaçu, sown on 13/10/2022, with the following characteristics: 13 plants per meter, spacing of 0.45 m between rows and population density of 288,888 plants per hectare, the first application carried out on 13/10/2022, the second application carried out on 04/11/2022 and the third application carried out on 12/11/2022 and ending the trial with the harvest on 10/03/2023. The experimental design used was randomized blocks with 10 treatments and 4 replications.  In the following results, the treatments show the formulated products with their respective doses in l/ha. The application times used were A: pre-planting desiccation; B: post-emergence; C: post-emergence.
