(IF 2.5) Pub Date : 2024-07-30 Marvin Pec, Paolo Salazar-Mendoza, Diego M. Magalhães, Italo Delalibera Jr., José Maurício S. Bento
The use of endophytic entomopathogenic fungi (EEF) represents a promising strategy to boost plant resistance in crops against both biotic and environmental stresses. However, the mechanisms by which this inoculation influences constitutive and herbivore-induced defenses to protect plants against pest insects remain unclear. To address this gap, we investigated whether the inoculation of the EEF can

Analyzing the benefits and limitations of advanced 2,4-D herbicide delivery systems Crop Prot. (IF 2.5) Pub Date : 2024-07-30 Vera V. Butova, Tatiana V. Bauer, Vladimir A. Polyakov, Vishnu D. Rajput, Tatiana M. Minkina
Herbicides are pivotal in modern agriculture, efficiently managing weeds and supporting sustainable farming. One of such herbicides is 2,4-dichlorophenoxyacetic acid (2,4-D), a synthetic auxin that targets broad-leaved weeds. It's praised for controlling various weeds with minimal injury to monocot plants. Innovative delivery methods for 2,4-D, like slow release and targeted systems, offer benefits

Effect of row distance on plant architecture, weed suppression and yield of silage maize (Zea mays L.) and soybean (Glycine max (L.) Merr.) in a pesticide-free cultivation system in Southern Germany Crop Prot. (IF 2.5) Pub Date : 2024-07-26 Dina Otto, Sebastian Munz, Waqas Ahmed Malik, Simone Graeff-Hönninger
Conventional farming prioritizes monocultures and synthetic chemicals to secure high yields. However, there are a growing number of initiatives worldwide to reduce or eliminate the use of pesticides. One option for pesticide-free weed management is the adjustment of sowing pattern (row distance, plant arrangement, sowing density). This study investigated the effects of an equal distance sowing versus

Trichoderma gamsii, a new pathogen causing disease on cultivated mushroom Cordyceps militaris in China Crop Prot. (IF 2.5) Pub Date : 2024-07-26 Huanhuan Peng, Yunlong Cong, Yitong Zhao, Zhenghui Liu, Yu Li
The fungal disease of has become the primary disease during the cultivation of . . However, some of the causal organism remains unclear. During our investigation in 2020–2022, three fungal strains were isolated from both the mycelium and fruiting bodies of . in mushroom farms located in Changchun. The observed disease incidence was approximately 20%. White villous mycelium on the surface of hyphae

Extraction of ginkgolic acids from Ginkgo biloba L. exocarp and their efficacies against Tetranychuscinnabarinus Crop Prot. (IF 2.5) Pub Date : 2024-07-26 Jingjing Ren, Puxing Hou, Qianxi Yue, Jianxiong Xie, Bin Zhang, Zhiqing Ma, Hua Wu
Spider mites cause substantial economic losses and are difficult to control in agricultural systems. L. extract has potential as an acaricide, although its specific acaricidal components have yet to be identified. We used bioassay-guided isolation to isolate and purify three main ginkgolic acid (GA) compounds (C13:0, C15:1, and C17:1). Their chemical structures were identified as H, C, and IR, respectively

The use of essential oils as an alternative for the control of Tetranychus urticae (Acari: Tetranychidae) Crop Prot. (IF 2.5) Pub Date : 2024-07-26 Aline Marjana Pavan, Tairis Da-Costa, Amanda Janner Marques, Eduardo Miranda Ethur, Bárbara Buhl, Geraldo Luiz Gonçalves Soares, Noeli Juarez Ferla
Considering that the use of essential oils is a promising technique and a valuable alternative in the control of unwanted organisms, this study aimed to chemically characterize the essential oil of (Loefl.) O. Kunze (Asteraceae) through gas chromatography, as well as to evaluate the repellent and acaricidal effect of the essential oils from and (Less.) Joch.Müll (Asteraceae) against Koch (Tetranychidae)

Chemical weed control in direct-seeded rice using drone and mist flow spray technology Crop Prot. (IF 2.5) Pub Date : 2024-07-25 Muhd Azlan Abd Ghani, Abdul Shukor Juraimi, Ahmad Suhaizi Mat Su, Muhammad Saiful Ahmad-Hamdani, A.K.M. Mominul Islam, Mst Motmainna
Weeds are the primary pest that reduces crop yield. Herbicide-based weed control is an efficient strategy for farmers, offering economically feasible weed management for agricultural crop production. The effectiveness of agrochemicals relies on the correct calibration and exact calculations of the rates needed per unit area, uniform distribution over treated surface and spraying conditions. The current
