“…P. capsici: Disease severity was evaluated on a 0-9 scale according to an evaluation system of Yang et al [25] with slight modifications, where 0 = there is no evidence of infection; 1 = ≤ 5% of the stem surface is diseased; 3 = 5-15% of the stem surface is diseased; 5 = 16-25% of the stem surface is diseased; 7 = 26-50% of the stem surface is diseased; 9 = ≥ 50% of the stem surface is diseased. The disease index and control efficacy for each fungicide were calculated according to the Equations (6) and (7) [26].…”

Processing pepper planting and processing have become an important red pillar industry in Xinjiang. With the continuous growth of processing pepper planting areas in Xinjiang, diseases and pests are increasing year by year. The aim of this study was to compare the droplet deposition and control efficiency of unmanned aerial vehicle (UAV) and electric air-pressure knapsack (EAP) sprayers on a processing pepper field. The UAV sprayer had a poor droplet coverage rate, droplet density, and deposition uniformity, but displayed the best deposition (1.01 μg/cm2, which was 98% more than the EAP sprayer). The control efficacy of the UAV sprayer on processing pepper fields with Phytophthora capsici and aphids was slightly lower than that of the EAP sprayer. When the UAV sprayer was used to control processing pepper diseases and pests, it could reduce the pesticide dosage on the premise of ensuring the control effect. Further study of the residue of high concentration pesticides in pepper fruit and environment sprayed by UAVs are needed.

“…Основна проблема його застосування полягає в тому, що хоча виробники комерційних препаратів на основі флуазинаму рекомендують застосовувати його у грибівництві для захисту врожаю від мікопатогених грибів, наукових публікацій з цього питання не існує. Проте, встановлена досить широка доказова база доцільності та безпечності використання цього фунгіциду в сільському господарстві для захисту зернових та овочевих культур від фітопатогенних грибів (Matheron, Porchas, 2004;Dai et al, 2018;Jeschke et al, 2019). Нами показано, що за дії флуазинаму відбувалися суттєві зміни мікроморфологічних ознак міцелію штамів C. mycophilum.…”

“…However, the Southern corn leaf blight (SCLB) caused by Bipolaris maydis can lead to millions of losses in the production of maize [ 7 ]. Traditionally, chemical agents were generally applied to control SCLB, including carbendazim and mancozeb [ 8 , 9 ]. Unfortunately, some stains of B. maydis had developed resistance to commercially available fungicides in many regions [ 9 ].…”

Bipolaris maydis causes southern corn leaf blight and inflicts huge losses on maize production. In order to search for new natural products from insect gut bacteria to control plant fungal disease, 86 actinomycetes were isolated from more than 50 insect guts, in which crude extract of strain SN5431 showed significant inhibition of the mycelial growth of B. maydis. The strain was identified and named as Streptomyces sp. SN5431. Six compounds were obtained from the crude extract of strain SN5431, which includes five new γ-butyrolactones named as tiuslactone A–E (1–5), and one new long chain ester named as tiusester (6). Their structures were determined using NMR and HRESIMS data and then combined with the spectroscopic data of known similar compounds. Tiuslactone B (2) showed powerful antifungal activity against B. maydis. These results indicated metabolites of insect gut bacteria have the potential to be the leading compounds for the control of corn leaf blight.
