ABSTRACT
ABSTRACT Although the knowledge on agricultural using of biostimulants increases, there is still little information on their interactions with other chemicals i.e. herbicides. The aim of the study was to assess the influence of popular herbicides (MCPA + dicamba, dicamba + triasulfuron, florasulam+2,4-D) used with and without biostimulants based on seaweed extract (Kelpak) and nitrophenols (Asahi) on weed control efficiency, yield and quality of the crop. Field trial was carried out in the years 2014 and 2015 in the Institute of Plant Protection - National Research Institute in Poznan (Poland). The experiment was established on spring wheat cv.'Torridon', in 4 replications, using randomized block design. In the experiment two variants of application were tested. In the first variant preparations (herbicide and biostimulant) were applied as tank mixtures at the crop growth stage BBCH 30 and in the second variant in some combinations herbicide application was followed by biostimulant used alone. Weather conditions had a profound impact on tested preparations activity. Addition of biostimulants to herbicide had not affected weed control efficacy but application of herbicide and biostimulant mixture revealed its influence on yield parameters of wheat. Biostimulants influenced yield quality parameters e.g. by enhancing gluten amount in grains.
RESUMO
RESUMO Embora o conhecimento sobre o uso agrícola de bioestimulantes aumente, ainda há pouca informação sobre suas interações com outros produtos químicos, como por exemplo, herbicidas. O objetivo desta pesquisa consistiu em avaliar o efeito dos herbicidas MCPA + dicamba, dicamba + triasulfuron + e florasulam + 2,4-D, usados com bioestimulantes a base de extratos de algas marinhas (Klepak) e nitrofenóis (Asahi) sobre a eficiência do controle de plantas daninhas e o rendimento da produção das plantas cultivadas. Os estudos de campo foram realizados nos anos de 2014 e 2015 pelo Instituto de Proteção de Plantas - Instituto Nacional de Pesquisas em Poznań (Polônia). O experimento foi realizado na cultura do trigo, cultivar 'Torridon' com quatro repetições. Foram estudadas diferentes opções de mistura de herbicidas versus bioestimulantes que foram aplicados em mistura de tanque ou o bioestimulante foi aplicado três dias após a aplicação do herbicida. As condições climáticas afetaram o desempenho das misturas utilizadas. A adição de bioestimulante ao herbicida não modificou a eficiência do controle de plantas daninhas, mas revelou grande influência nos parâmetros de produtividade do trigo. O uso de bioestimulantes provocou a melhora da qualidade dos grãos, aumentando o teor de glúten.
