Chloride occurs predominantly as Cl in soil, plant, and considering as a micronutrient largely excluded by plants due to its ubiquity and abundance in nature. It is an essential micronutrient of higher plants and participates in several physiological metabolism processes.

Chloride (Cl) has traditionally been considered harmful to agriculture because of its toxic effects in saline soils and its antagonistic interaction with nitrate (NO3), which impairs NO3 nutrition. It has been largely believed that Cl antagonizes NO3 uptake and accumulation in higher plants, reducing crop yield. However, we have recently uncovered that Cl has new beneficial macronutrient functions that improve plant growth, tissue water balance, plant water relations, photosynthetic performance, and water-use efficiency (WUE). Increasing plant biomass indicates in turn that Cl may also improve nitrogen use efficiency (NUE).

氯化物主要以Cl的形式存在于土壤和植物中，由于其在自然界中的普遍存在和丰富，被认为是一种被植物排除在外的微量营养素。它是高等植物必需的微量营养素，参与多种生理代谢过程。包括渗透和气孔调节，光合作用中氧的进化，抗病性和耐受性。氯化物(Cl)一直被认为对农业有害，因为它在盐碱地中的毒性作用及其与硝酸盐(NO3)的拮抗相互作用，从而损害NO3的营养。人们普遍认为，Cl会抑制高等植物对NO3的吸收和积累，从而降低作物产量。然而，我们最近发现Cl具有新的有益的常量营养素功能，可以改善植物生长、组织水平衡、植物水分关系、光合性能和水分利用效率(WUE)。增加植物生物量表明Cl也可能提高氮素利用效率(NUE)。钠离子和钾离子周围水的结构是检验相互作用电位质量的关键，它们并没有完全对准它们的电场，而是倾斜的。这种倾斜对钾的影响比对钠的影响更明显。钠的水合数量限制在5个或6个分子，而钾的水合数量则在5到10个分子之间。Na和K之间最显著的能量差异存在于第一壳层。在此条件下，水分子之间的相互作用非常强，Na对土壤盐分的影响大于K。但在盐胁迫下，Na含量的增加往往伴随着Cl的积累和K的损失。由于氮素有效性是陆地植物生长的瓶颈，农业中频繁使用的过量NO3施肥成为世界范围内的一个主要环境问题，导致作物特别是蔬菜叶片NO3过量积累，对人体健康构成潜在风险。旨在通过减少NO3施肥来提高植物氮素利用效率(NUE)的新耕作方法将促进更健康和更可持续的农业。考虑到植物体内Cl和NO3的强相互作用，我们已经验证了Cl是否确实影响植物体内NO3的积累和NUE。据我们所知，我们首次提供了一个直接的证明，表明Cl与损害NO3营养相反，促进了植物对NO3的利用，提高了NUE。这主要是由于Cl -提高了N - NO3利用效率(NUTE)，而当NO3作为唯一N源时，Cl -对N - no -吸收效率(NUPE)的影响很小或中等。在种内和种间水平上，叶片Cl含量与NUE / NUTE或植物生长之间存在明显的正相关关系。优化NO3与Cl的比例是提高作物产量和质量、农业用地可持续性以及减少NO3对环境和人类健康的负面生态影响的有用工具。

Field experiments were conducted at Naser fields in Beni-Suef Governorate, Egypt in the growing seasons 2018/2019 and 2019/2020 to study the population fluctuations of the cabbage white butterfly, Pieris rapae (L.) and its associated parasitoid and predatory species in cabbage plantations. P. rapae has from three to four generations per season on cabbage. Five primary parasitoid species; Trichogramma buesi V., Cotesia glomerata (L.), Hyposoter ebeninus Grav., Brachymeria femorata Panz and Pteromalus puparum L. were found parasitizing on the developmental stages of this pest. The predator Chrysoperla carnea Stephens, was recorded. Combined effect of three weather factors on the population density of P. rapae was studied.

The objective of the study was to assess the potential effect of honey and bee venom (BV) on nephrotoxicity caused by LPS (Lipopolysaccharide) and CCl4 (Carbon Tetrachloride) in rats. Sixty-four male albino rats of an average weight of 120–150 g were included in this study. Rats were divided into 8 equal groups of 8. The results showed that treatment with LPS/CCl4caused in a significant increase in serum urea, creatinine as well as uric acid. The use of honey (25 mg/kg b.wt.) and BV (1 mg/kg b.wt.) attenuates to LPS and CCl4 induced renal dysfunction was demonstrated. Honey and/or BV may therefore be a potential therapeutic method to prevent LPS/CCl4-induced renal dysfunction.
