“…The results of this study showed that different herbicides exhibited high potency in inhibiting mycelial growth of all isolated rhizosphere fungi of yellow pepper (C.annum.Var Nsukka yellow). This inhibition of mycelial growth of fungi by herbicide application is consistent with previous studies (Mohiuddin and Mohammed, 2014;Pakdaman andGoltapeh, 2014 andWilkinson andLucas, 1969). Although all the herbicides tested inhibited fungal growth at the recommended field application rates, it is worthy to note that none of the tested herbicides displayed fungal growth stimulation.…”

In vitro screening of five selected herbicides at different concentrations on rhizosphere mycoflora from yellow pepper (capsicum annum L var. Nsukka yellow) seedlings at Nsukka were investigated. The herbicides employed for this study were Paraquat, Glyphosate, Primextra, Atrazine and Linuron. The isolated rhizosphere mycoflora organisms screened were Rhizopus stolonifer (Ehren ex. Fr) Lind, Trichoderma harmatum Bain aggr; Aspergillus niger Van Tiegh; Sclerotium rolfsii Sacc; Penicillium sp; Alternaria sp; Fusarium solani (Mart) Sacc and Rhizoctonia sp. The results showed that all the herbicides at different concentrations of 0.5 µg/ml a.i, 1.0 µg/ml a.i, 2.0 µg/ml a.i, 5.0 µg/ml a.i and 10.0 µg/ml a.i inhibited the mycelial growth of the isolated rhizosphere fungi. Growth inhibition of the rhizosphere fungi increased with increasing concentrations of each herbicide. Paraquat, Glyphosate and Atrazine showed higher inhibition potency on all the fungal mycelial growth than Primextra and Linuron. The significance of these results is discussed.

“…However, the activity of certain diazotrophic bacteria can be compromised due to some antagonistic stimulus, such as soil physicochemical conditions and the toxicity of some pesticides (Hungria, 2011). Research conducted by Gallori et al (1991) and Mohiuddin and Mohammed (2013) reported the ability of the captan active ingredient to reduce bacterial growth and negatively affect nitrogenase activity. This inference corroborates the results obtained in this study.…”

The application of biological products containing diazotrophic bacteria in the seed has been highlighted as an alternative to reduce the use of nitrogen fertilizers; however, the chemical treatment of the seeds may negatively affect the survival rate of these microorganisms in the soil. The effects of the application of captan (fungicide) and thiodicarb (insecticide) in association with the inoculation of Azospirillum brasilense were investigated in this study for the corn crop. The research was conducted under greenhouse conditions at Universidade Estadual do Centro-Oeste (UNICENTRO), in Guarapuava, Paraná, Brazil, and under laboratory conditions at the Universidade Federal da Fronteira Sul (UFFS), in Laranjeiras do Sul, Paraná, Brazil. A completely randomized experimental design with eight treatments and four replicates was used. The treatments were as follows: control; A. brasilense; captan; thiodicarb; captan + thiodicarb; A. brasilense + captan; A. brasilense + thiodicarb; A. brasilense + captan + thiodicarb. The germination and seedling growth rates were evaluated in the laboratory. In the greenhouse were measured the growth of the roots and shoots until the V8 corn growth stages. The use of A. brasilense alone resulted in higher plant growth when compared to the control treatment, whereas the association of A. brasilense with captan and thiodicarb resulted in a similar response to the uninoculated and control treatments. These results suggest that there was a possible toxic effect of seed treatment with these products. The use of captan and thiodicarb interfere in the interaction of diazotrophic bacteria with root growth, affecting the germination rate and initial corn growth.

“…However, their total counts dropped significantly after 30 days, and the negative effect was more prominent in sand. Mohiuddin & Mohammed (2013) also reported a significant reduction in bacteria counts in their experiments with herbicides (metribuzin and 2.4-D) and a fungicide (carbendazim). The strongest inhibitory effect was found on the 14 th day of the experiment and it was noted in all treated pots.…”

Microbial activity in different soils in response to metribuzin treatment

et al. 2019

The effect of metribuzin on soil microorganisms and their enzymatic activity, as well as the amount of metribuzin residues, greatly depend on the type of soil and its physico-chemical properties. A laboratory experiment was set up to determine the effects of metribuzin on different groups of microorganisms and dehydrogenase activity in loamy and sandy soils. The amounts of metribuzin residues in those soils were also determined. The following concentrations were tested: 12.0, 24.0, 120.0 and 1200.0 mg a.i. kg-1 soil. Samples were collected 3, 7, 14, 30 and 45 days after metribuzin application. Metribuzin acted inhibitively on total bacteria counts in both types of soil: 6.9% in loamy and 7.9% in sandy soils. Actinomycetes counts decreased over the first 14 days after metribuzin treatment by 15.6% in loamy and 8.1% in sandy soil. However, starting with the 30 th post-treatment day, their number either increased or remained at the control level. Fungi counts increased by 6.0% seven days after the application of the two highest concentrations. In sandy soil, fungi counts were significantly reduced by 29%. Metribuzin treatment significantly reduced the activity of dehydrogenase enzyme in both types of soil. Only the highest test concentration applied to the sandy soil showed a stimulating effect (33.2 %). Degradation data showed that the measured amounts of metribuzin decreased over time in both types of soil at all four test concentrations. The results showed that the extracted amounts of metribuzin active ingredient at all its test concentrations were greater in the sandy type of soil. Loamy soil was shown to have a better sorption capacity due to its higher contents of organic matter and clay.
