Cucumber anthracnose is a destructive fungal disease caused by Colletotrichum orbiculare. Common control strategies include chemical fungicides. However, this can lead to the development of pathogenic resistance. Therefore, it is necessary to identify natural compounds or microorganisms to develop new chemicals and the biological control of fungal pathogens. Isolate GT2, a bacterial isolate from soil samples collected in Shimane Prefecture, Japan, significantly inhibited in vitro mycelial growth and conidial germination of C. orbiculare, indicating a fungicidal effect against this pathogen. Furthermore, anthracnose lesion formation...

Allelopathic plants release phytotoxic compounds that contribute to their invasiveness by suppressing nearby species. However, it remains unclear which exact mode of action (MOA) underlies the allelopathy. This study explores the allelopathic mechanisms of Turnera subulata on the recipient indicator plant choy sum using a metabolomics approach. Briefly, T. subulata leaf aqueous extracts (LAEs) at different concentrations (0.0, 0.1, 1.0, 10.0, 50.0, and 100.0 mg/mL) were sprayed at 100 mL/m2 on choy sum seedlings at the two to three leaf stage. After 21 days, the Soil Plant Analysis Development (SPAD) values and photosynthetic...

The current study presents the first documented interaction between the date palm scale insect (Parlatoria blanchardi) and the black rats (Rattus rattus). For a year, this study investigated whether R. rattus could serve as a means of phoresy for the survival of P. blanchardi and the potential risks associated with its spread to date palm stands. Our research revealed a prevalence rate of P. blanchardi on R. rattus of 5.79% during the year, while a higher rate of 9.33% was observed during a specific five-month period. The mean infestation intensity was 3.39 parasites/rat during these five months. Statistical...

The current study aimed to characterise indigenous Bacillus thuringiensis (Bt) strains for their potential use in agricultural broad-spectrum pest control. Twenty-nine Bt strains were isolated from soil in southeastern Kazakhstan. All isolates were Gram-positive and formed endospores. Species identification was conducted by sequencing the gyrase B (gyrB) gene. The nucleotide sequences of the amplified gyrB gene regions were compared with those in the NCBI database, confirming that the isolates were native Bt strains with high homology to known Bt strains (99–100%). In addition, the strains were screened for the presence...

Cabbage (Brassica oleracea var. capitata L.) and onion (Allium cepa L.) are two of the most important vegetables in the world, and many insect pests are a problem in their production. Currently, especially in Europe, restrictions on the use of pesticides are increasingly being encouraged, so the need to find and use alternative methods is increasingly urgent. Cultural control of insect pests using companion plants, including cover crops, intercrops, and trap crops, has been proven to help manage these insect pests. Companion plants reduce plant insects primarily by disrupting host-seeking activity, disrupting oviposition,...

Strawberry mild yellow edge virus (SMYEV) was detected in 116 samples out of 423 collected from strawberry plants grown in commercial and experimental plantations in seven provinces of Poland. The number of samples infected with strawberry mottle virus (SMoV) accounted for 84.6% of the 26 SMYEV-positive samples selected for sequence analysis. The nucleotide sequence similarity of the coat protein (CP) gene of 26 selected SMYEV isolates ranged from 84.8% to 100%, and 81.4–99.5% identity was found between these isolates and 48 SMYEV strains from different countries. The CP region's phylogenetic analysis showed that most isolates from Poland clustered...
