The aim of the present review is to summarize selenium’s connection to pests. Phytopharmaceuticals for pest control, which increase the pollution in the environment, are still widely used nowadays regardless of their negative characteristics. The use of trace elements, including selenium, can be an alternative method of pest control. Selenium can repel pests, reduce their growth, or cause toxic effects while having a positive effect on the growth of plants. In conclusion, accumulated selenium protects plants against aphids, weevils, cabbage loopers, cabbage root flies, beetles, caterpillars, and crickets due to both deterrence and toxicity.

The aim of the research was to determine the effect of soil contamination with diesel oil (0; 5; 10 and 15 cm3 kg−1 of soil) on the content of trace elements in the aboveground parts of oat (Avena sativa L.). Stabilised sewage sludge was used to mitigate the likely negative impact of diesel oil on the plant. Growing soil contamination with diesel oil had a significant impact on the content of trace elements in the aboveground biomass of oat. In the series without sewage sludge, the contents of the analysed elements, except for chromium, zinc, copper and cobalt, were positively correlated with the increasing doses of diesel oil. The largest increase in the content was recorded in the case of manganese. The sewage sludge used to reduce the influence of diesel oil on the chemical composition of oat had a positive effect on the content of the analysed trace elements. Compared to the series without the addition of a stabilised sewage sludge, it contributed to a reduction in the average content of chromium, nickel, copper, manganese and cobalt in the aboveground parts of oat plants. No significant effect of the applied remediation treatment was noted for cadmium, and the results were equivocal for iron.

Rumex obtusifolius is a troublesome weed widely spread in temperate grasslands and can be potentially used for detection of soils contaminated by trace elements. We asked how emergence and survival of its seedlings are affected by application of quick lime (Ca) and superphosphate (P) additives in soils contaminated by trace elements. We performed the pot seeding experiment with slightly acid Litavka soil contaminated by arsenic (As), cadmium (Cd), lead (Pb), and zinc (Zn) and alkaline Malín soil contaminated by As, Cd, and Zn. We used a control without any additives, Ca and P treatments in both soils. Higher and quicker emergence, together with substantially higher mortality of seedlings, was recorded in Litavka than in Malín. A positive effect of the Ca treatment on seedlings was recorded in Litavka, but a negative in Malín. Small seedlings with narrow and long leaves of reddish colour were recorded in Litavka in the control and in the P treatment both with high availability of Zn, Cd, and Pb. In the Ca treatment, leaves of seedlings were more elliptic and less reddish. In Malín, seedlings were green and substantially more vital in the control and in the P treatment than in Litavka. In the Ca treatment, small and unviable seedlings were recorded. Seedlings of R. obtusifolius are sensitive on high availability of Ca, Zn, Cd, and Pb in the soil.

Agricultural productive services provide a new entry point to solve the “labor dilemma” and contributes to the sustainable development of the apple industry. In this study, we establish a random frontier model with the Translog production function to analyze the influence of productive services on the technical efficiency of apple production based on a microscopic survey data of 661 apple farmers. The results indicate that the purchasing proportions of productive services are obviously different among the different links of apple production, while those among different regions are not obvious. Overall, productive services have a positive effect on improving the technical efficiency of apple production, but productive services in different links have a different effect; specifically, productive services in the bagging link have a positive effect on the technical efficiency of apple production, productive services in the pest controlling link have a negative effect, and productive services in other links have no significant effect. We suggest that policymakers should promote the orderly development of agricultural productive services, focus on improving the popularity of productive services in bagging links, and improve the quality of productive services in the pest control link.

And Oxidative Stress

Trigonella foenum-graecum L. is enriched with many active ingredients. TFG oil was evaluated for its protective effect against deltamethrin toxicity in rats. Rats of the control group were administered saline. The 2nd group was administered deltamethrin (DLM) orally at a concentration of 15 mg/kg body mass. The 3rd and 4th groups were administered DLM at a concentration of 15 mg/kg body mass and were fed diets containing 2.5% and 5% TFG oil, respectively. DLM intoxication reduced red blood cell and platelet counts, hemoglobin concentration, and hematocrit value while it induced leucocytosis. Furthermore, it increased serum levels of lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, γ-glutamyltransferase, triglycerides, cholesterol, uric acid, urea, and creatinine; increased hepatic, renal, and brain lipid peroxidation; decreased serum acetylcholine esterase level; and decreased hepatic, renal, and brain antioxidant markers’ activities. However, TFG oil kept the studied hematological and biochemical parameters within normal ranges. In addition, it prevented lipid peroxidation and oxidative stress induced by DLM intoxication in a dose-dependent manner. Therefore, these results indicated that TFG oil inhibited the toxic effects of DLM on hematological and biochemical parameters as well as oxidative status by its free radical scavenging and potent antioxidant activities, and it appeared to be a promising protective agent against DLM-induced toxicity.

Poultry Farming

Trace elements in the body of the bird are in small quantities, but their role in productivity remains important. In order to get a quality carcass at the slaughterhouse, you need a constant supply of nutrients and, last but not least, microelements. Zinc and Manganese are essential trace elements that affect the growth and development of birds. And their deficiency in the body has a negative effect on the productivity of birds. In the diet of broilers trace elements are mainly added with a premix in the form of inorganic salts (sulfates, carbonates). However, these micronutrient compounds in the body of the bird are insufficiently absorbed, and increasing the dose of their introduction can cause toxicosis. Therefore, in order to prevent microelementosis, it is more appropriate to use organic compounds (chelates), which have a much higher level of bioavailability and less release into the environment. This review article describes the prophylactic efficacy of Zinc and Manganese chelates in micronutrient deficiencies in broiler chickens and laying hens. With a deficiency of a particular trace element develop metabolic disorders and other pathologies (perosis, etc.). Based on the presented data, it can be concluded that the use of organic forms of trace elements in poultry feeding is a better alternative to inorganic sources, as they can be used in smaller quantities. But due to their greater bioavailability, they are better absorbed, which has a positive effect on the productivity of broilers. Since knowledge about the use of chelated forms of trace elements in comparison with inorganic forms (salts, sulfates, etc.) in the diet of poultry is still poorly understood, it is necessary to further conduct research to prevent micronutrient deficiencies in these compounds.

The tomato leaf miner, Tutaabsoluta causes serious losses in production. It can feed on all the green parts of the tomato and can cause up to 100% damage if not controlled. Presently, the most effective method of pest control is the use of chemicals. The purpose of this study is to give alternative solutions based on natural products. The objective was to know the biocidal power of the aqueous extracts of Crataevareligiosa leaves on T. absoluta. The work was conducted on a field at the Niayes area. Three formulations were used: formulation with dry leaves (200g/l, 150g/l and 100g/l), formulation with fresh leaves (200g/l) and soapy formulation (100g Crataeva + 25g soapy) and two controls (C0, S). Each treatment was repeated twice as well as the controls. The results showed a significant decrease (P <0.0001) of the larvae compared to the blank control. However, the fresh formulation (200g/l) had double effect by reducing the number of pest larvae and a positive effect on number of the predator N. tenuis in addition to a positive impact on the agronomic traits. The dry formulation, which certainly reduced the T. absoluta larvae, had no impact on N. tenuis and H. armigera.
