“…Nevertheless, phytotoxicity and a high variability in the response in host plants in the field have been reported, which raises questions about their feasibility in crop protection (Reglinski et al, ). Therefore, interest in selecting beneficial microorganisms with which to develop biological control agents (BCAs) has increased as a result of microbial biopesticides being an indispensable and powerful tool in IPM (Matyjaszczyk, ). While strains of bacteria, fungi and viruses to manage plant diseases and pests are now commercially available (Matyjaszczyk, ; Montesinos & Bonaterra, ), because of the influence biotic and abiotic factors have, the efficacy of the biological products may vary between trials or decrease in field conditions (Sundin, Werner, Yoder, & Aldwinckle, ).…”

The use of lactic acid bacteria (LAB) to control multiple pathogens that affect different crops was studied, namely, Pseudomonas syringae pv. actinidiae in kiwifruit, Xanthomonas arboricola pv. pruni in Prunus and Xanthomonas fragariae in strawberry. A screening procedure based on in vitro and in planta assays of the three bacterial pathogens was successful in selecting potential LAB strains as biological control agents. The antagonistic activity of 55 strains was first tested in vitro and the strains Lactobacillus plantarum CC100, PM411 and TC92, and Leuconostoc mesenteroides CM160 and CM209 were selected because of their broad‐spectrum activity. The biocontrol efficacy of the selected strains was assessed using a multiple‐pathosystem approach in greenhouse conditions. L. plantarum PM411 and TC92 prevented all three pathogens from infecting their corresponding plant hosts. In addition, the biocontrol performance of PM411 and TC92 was comparable to the reference products (Bacillus amyloliquefaciens D747, Bacillus subtilis QST713, chitosan, acibenzolar‐S‐methyl, copper and kasugamycin) in semi‐field and field experiments. The in vitro inhibitory mechanism of PM411 and TC92 is based, at least in part, on a pH lowering effect and the production of lactic acid. Moreover, both strains showed similar survival rates on leaf surfaces. PM411 and TC92 can easily be distinguished because of their different multilocus sequence typing and random amplified polymorphic DNA profiles.

“…Some products can therefore be legally placed on the market without any registration, or they can be registered under the law for fertilisers, in spite of the fact that they can also be useful in plant protection. This issue has been previously discussed, as well as the fact that the approach of a given MS regarding the level of regulation of this group of products varies widely …”

Following the obligatory implementation of integrated pest management in the European Union (EU), the plant protection means suitable for application in organic agriculture attracted the attention of quite a wide group of potential users. In spite of the common rules of organic production, as well as the uniform principles of placing plant protection products on the market, the availability of products that can be legally used in organic crop protection differs significantly among the Member States. There is a uniform list of 10 basic substances that can be used in the protection of organic crops throughout the entire EU. Twelve Member States have official registers of plant protection products for use in organic agriculture, and the total number of qualified products per country varies from 11 in Lithuania to 576 in Italy. Some products that improve plant vigour or resistance and may be of use in protection of organic crops are placed on the market as biostimulants. They fall under the law that governs fertilisers and the systems of their registration vary widely among the Member States. In addition, there exist a number of products that have been legally introduced onto the markets of some Member States without registration as a consequence of a loophole in the law. The use of unregistered products in organic agriculture raises some doubts, but currently it seems that there is no legal basis on which to explicitly prohibit the practice. © 2017 Society of Chemical Industry.

“…Neste contexto, o uso indiscriminado de produtos químicos para controle de D. fovealis pode estar causando contaminação ambiental e humana, aumento de resíduos em morangos e efeitos deletérios sobre organismos não-alvos. Deste modo, há a necessidade de se avaliar estratégias que possibilitem implementar um programa de Manejo Integrado de Pragas (MIP) para D. fovealis, sendo o controle biológico uma ferramenta a ser priorizada (MatyjasZcyk 2015).…”

Seletividade de inseticidas reguladores de crescimento e botânico no parasitismo de três espécies de Trichogramma em ovos de Duponchelia fovealis Zeller (Lepidoptera: Crambidae)

Resumo. A mariposa Duponchelia fovealis Zeller (Lepidoptera: Crambidae) é uma espécie exótica que se tornou praga-chave do morangueiro no Brasil, causando severos danos nas folhas e frutos. Dentre os grupos químicos que são promissores para o controle da praga, pela seletividade aos inimigos naturais e menor toxicidade, destacam-se os inseticidas reguladores de crescimento de insetos e os inseticidas botânicos. Assim, visando contribuir com a elaboração de estratégias de manejo da praga, o objetivo deste trabalho foi avaliar em laboratório o efeito de cinco inseticidas reguladores de crescimento e um botânico sobre o parasitismo e emergência de três espécies de Trichogramma em ovos de D. fovealis. Os inseticidas testados foram formulados a partir de diflubezuron, lufenuron, pyriproxyfen, methoxyfenozide, tebufenozide e azadirachtin. Ovos de D. fovealis foram imersos por cinco segundos em uma das caldas químicas e, após 1 hora, oferecidos ao parasitismo de Trichogramma galloi Zucchi, Trichogramma exiguum Pinto & Platner,or Trichogramma atopovirilia Oatman & Platner. Foi avaliada a ação dos inseticidas sobre o parasitismo e a emergência da geração F1, sendo os produtos classificados quanto a sua toxicidade conforme índices propostos pela IOBC/WPRS. Os inseticidas afetaram de modo distinto o parasitismo e a emergência dos parasitoides, indicando uma tolerância diferenciada entre as três espécies de Trichogramma. Os inseticidas foram classificados como inócuos ou levemente nocivos para as três espécies avaliadas. Entretanto, lufenuron foi moderadamente nocivo para T. galloi, causando a maior redução no parasitismo deste parasitoide.Selectivity of growth regulators and botanical insecticides in the parasitism of three Trichogramma species on eggs of Duponchelia fovealis Zeller (Lepidoptera: Crambidae)Abstract. Duponchelia fovealis Zeller (Lepidoptera: Crambidae) is an exotic moth species which has become a key pest of strawberries in Brazil, causing severe damage in leaves and fruits. Insect growth regulators and botanical insecticides are promising chemical groups to control this pest due to their selectivity to natural enemies and to their lower toxicity. The objective of this study was to evaluate the effect of five insect growth regulators and one botanical insecticide on the parasitism and emergence of three Trichogramma species on eggs of D. fovealis in the laboratory, in order to develop pest management strategies. The insecticides utilized in the tests were formulated from Diflubenzuron, Lufenuron, Pyriproxyfen, Methoxyfenozide, Tebufenozide, and Azadirachtin. D. fovealis eggs were immersed for five seconds in each of the chemical mixtures and after one-hour were offered to Trichogramma galloi Zucchi, Trichogramma exiguum Pinto & Platner,or Trichogramma atopovirilia Oatman & Platner for parasitism. The insecticides were tested for their action on the parasitism and emergence of the F1 generation; the chemicals were then classified for their toxicity according to indices proposed by IOBC/WPRS. The insecticides affected parasitism and emergence differently, indicating different tolerances among the three Trichogramma species, and were classified as innocuous or slightly harmful to the three species under evaluation. However, lufenuron was moderately harmful to T. galloi and caused the highest reduction in parasitism by the parasitoid.
