The grain aphid (Sitobion avenae F.) is one of the most economically important cereal pests in Europe, causing both direct feeding damage (especially on the ears) and indirect virus transmission. For this reason, systematic monitoring of its intensity on crops and the damage it causes is crucial in the protection of winter wheat and other cereal plants in order to determine the current level of risk. The summary of observations illustrated the changing intensity of the occurrence of grain aphids over selected years in individual regions of the country and provinces.

A significant problem in the cultivation of plants, including winter oilseed rape in Poland is the increasing threat from pests, the appearance of new species and the increasing their activity, especially in the context of the observed climate changes. One of them is common across the country with varying degrees of pollen beetle – Brassicogethes aeneus (F.). The effect of the pest’s feeding is a weak or no silica formation, and thus an unfavorable effect on the obtained seed yield. The aim of the study was to analyze the damage of winter oilseed rape caused by pollen beetle in various regions of Poland in the years 2009–2019. The summary of the monitoring results of the pollen beetle showed the changing intensity of this pest occurrence over the selected years.

The most common bacterial diseases of mushrooms are the brown blotch caused by Pseudomonas tolaasii and the ginger blotch caused by Pseudomonas ‘gingeri’. Protection against bacterial infections consists in ensuring an appropriate microclimate in the cultivation rooms. The aim of the study was to assess the severity of bacterial blotch symptoms depending on the amount of irrigating water of mushroom cultivation. The crop was infected with a suspension of bacterial cells as equivalent to the application of 2.6 × 107 and 2.6 × 108 cells per 1 m2 of casing surface. The crop was watered in a fixed amount, i.e. 7, 10 and 14 litres per m2 of casing before the first flush and 6, 8 and 10 litres before the second flush. It was found that the amount of water had a significant impact on the severity of ginger blotch, especially in the first flush. The yield of infected mushrooms was significantly higher in the cultivation watered with the highest amount of water than in the other variants of the experiment. In the case of P. tolaasii statistically insignificant amount of infected mushrooms was observed in the cultivation with the highest amount of irrigating water. The severity of disease symptoms and the amount of water used to irrigate casing soil were highly or moderately correlated with each. It has been shown that a properly conducted watering treatment reduces the development of bacterial blotches on mushrooms.

The field research were carried out in 2019–2020, in Picobella sugar beet. The aim of the study was to develop an alternative weed control program without phenmedipham, desmedipham and chloridazone. The tested mixtures containing metamitron, ethofumesate, triflusulfuron-methyl, and lenacil used in various combinations together with the Atpolan BIO 80 EC adjuvant effectively controlled Fat hen (Chenopodium album) up to phase 1 of a pair of true leaves (BBCH 12). Excluding ethofumesate from mixtures of metamitron (700 g/ha) and triflusulfuron-methyl (15 g/ha) reduces the effectiveness of weed control. In the absence of ethofumesate, the effectiveness of the action is improved by increasing the dose of metamitron (1050 g/ha) and adding lenacil (100 g/ha) to the composition of the mixture. The conducted research proved that it is possible to effectively protect beet crops against Fat hen (Ch. album) after the desmedipham withdrawn and possible non-approval of phenmedipham and chloridazone.
该研究于2019-2020年在Picobella甜菜上进行。该研究的目的是开发一种不含苯美啶、地美啶和氯唑酮的替代杂草控制方案。所测试的混合物含有异氨氮、乙硫霉酸酯、三氟呋喃-甲基和lenacil，以不同的组合与Atpolan BIO 80 EC佐剂一起使用，有效地控制了肥母鸡(Chenopodium album)直到一对真叶(BBCH 12)的第1期。将甲氧呋喃(700克/公顷)和三氟呋喃-甲基(15克/公顷)的混合物中排除乙氧呋喃会降低杂草控制的有效性。在不含乙氧膦酸盐的情况下，通过在混合物的组合物中增加异氨氮的剂量(1050 g/公顷)和添加lenacil (100 g/公顷)来改善作用的有效性。本研究证明，在地米非安被撤销后，以及苯米非安和氯唑酮可能被不批准后，有效保护甜菜作物免受肥鸡(chalbum)的侵害是可能的。

The aim of the study was monitoring of the occurrence of fungal diseases of maize in south-eastern Poland. The observations were made in 2010–2021 in two fields conducted in a long-term monoculture in the Krzeczowice and Nienadówka. The health analyses were performer on the San (FAO 240) and Ronaldinio (FAO 260) maize varieties. The following maize diseases have been found: common smut of maize (Ustilago maydis), corn head smut (Sphacelotheca reiliana), eyespot (Kabatiela zeae), northern corn leaf spot (Helminthosporium spp.), common rust of maize (Puccinia sorghi), fusarium ear rot and fusarium stalk rot caused by fungi of the genus Fusarium. The most dangerous diseases are fusarium ear rot, fusarium stalk rot and common smut of maize. The most common fungal disease was eyespot. The appearance of these diseases was favored by some meteorological factors, such as hailstorm and pest feeding, especially frit fly, aphids, and European corn borer.

Field studies were carried out in 2017–2019 in Research and Education Centre Brody, Poznań University of Life Sciences, in order to assessment the impact of tested adjuvants on weed control in sugar beet. Treatments included phenmedipham + ethofumesate at recommended quantity (F + E, 200 + 200 g/ha) + metamitron (M, 700 g/ha) and phenmedipham + ethofumesate at reduced quantities (140 + 140 g/ha) without or with tested methylated seed oil (MSO 1, 2, 3) and standard adjuvants. Herbicides were applied three times after weed emergence. MSO adjuvants were more effective to F + E + M applied at reduced rates than standard adjuvants. The MSO adjuvants made it possible to obtain high and stable herbicidal efficiency of herbicides, regardless of varied weather conditions during and after their application. The root yield of sugar beet after application of herbicides with test adjuvants was higher than on the control and after application of reduced rates of herbicides without adjuvants.

Fungi are extremly diverse and beneficial organisms both for environment and industry; thus we are obliged to secure it’s biodiversity. There are several laboratory methods for fungi longterm preservation. The main goal is to secure their vitality and biological properties. Some of them are simple but the same time laborious, other demand specific equipment. Among the most popular methods we find: freez-drying, cryopreservation at –80°C and in liquide nitrogen. The most reliable is cryopreservation in liquid nitrogen. However even this method is not universal and siutable for all cultures.

The European Green Deal is an ambitious plan to build a sustainable economy for the European Union (EU). An integral part of this plan is the ”from field to table” strategy for a fair, healthy, environmentally friendly food system. Among other things, it calls for EU countries to reduce pesticide use by 50% by 2030. The national reduction target for the use of pesticides must not be less than 35%, and such has been adopted for Poland. Due to the systematic withdrawal of active substances contained in pesticides, the market of plant protection products requires constant monitoring and coordination. The conducted research shows the reduction of agricultural chemization as a process that requires a thoughtful and controlled selection of preparations used in the care of starch potato plantations. Applying available preparations in place of those that have been withdrawn from the market makes it possible to achieve the reducion target and production results at a similar level.

The aim of the study was to determine the effect of temperature on the growth of four species of acaropathogenic fungi of the genus Hirsutella (isolated from mites) grown in vitro on Sabouraud (SDA) and Czapek-Dox media. The effects of seven temperature ranges (5–35°C) were tested under laboratory conditions. Observations of colony growth were carried out every 5 days until day 25 by measuring the diameter of the colonies in mm. The growth rate of the test isolates was calculated in mm per day. The conducted studies showed that the thermal optimum of most of the tested isolates of acaropathogenic fungi of the genus Hirsutella was between 20°C and 25°C, with individual values varying depending on the type of medium on which the inoculum was developed. The fungus species with the highest temperature range of colony growth was Hirsutella thompsonii var. synnematosa. It was the only acaropathogenic fungus strain tested that developed on both types of culture medium, also at 35°C. The fastest growth rate of the tested isolates of acaropathogenic fungi was at 25°C. The cultures of the tested species of fungi reached larger sizes on the SDA medium rather than on Czapek-Dox medium.
本研究的目的是确定温度对在Sabouraud (SDA)和Czapek-Dox培养基上体外培养的四种毛癣菌属(Hirsutella)真菌生长的影响。在实验室条件下测试了7个温度范围(5-35°C)的影响。每隔5天观察一次菌落生长，直至第25天，以mm为单位测量菌落直径，以mm / d计算试验分离株的生长速率。所进行的研究表明，大多数被测试的毛孢属致病性真菌分离株的最适温度在20°C至25°C之间，其个体值因接种物的培养基类型而异。菌落生长温度范围最高的菌种是汤普森毛菌(Hirsutella thompsonii var. synnematosa)。这是唯一一种在35°C的两种培养基上都能培养的致病性真菌菌株。在25℃条件下，各分离株生长速度最快。被试菌种的培养物在SDA培养基上比在Czapek-Dox培养基上达到更大的大小。
