“…The general conclusion is that frequent and timely application of fungicides can ensure convincing control of blossom diseases and high yields. The results of this particular study are in general agreement with those of several investigators (Haq et al, 1994;Akhtar et al, 1998;Ihsan et al, 1999;Guizen et al, 2003;Anjum et al, 2016).

Anthracnose and powdery mildew are the two common maladies that attack mango at flowering and inflict heavy loss to fruit production. Seven organic and one inorganic fungicide were evaluated for their effectiveness against these diseases. In all, three bloom sprays were made, first at 25% flowering and two later sprays at 15-day intervals. Best results were achieved with Nativo 75% WDG (Tebuconazol+ Trifloxystrobin) which controlled anthracnose by 92.03% and powdery mildew by 90.19%. It was followed by Cabriotop 60% WDG (Metiram + Pyraclostrobin) which reduced incidence of these diseases by 89.08% and 88.04%, respectively, whereas Topsin-M 72% WP (Thiophanate methyl), Score 25% EC (Difenoconazol) and Shincar 50% SC (Carbendazim) provided less than 80% control. Topas 100% EC (Penconazole) and Vangard 25% EC (Tridamenol) were effective against powdery mildew (89.96% and 91.87%) and Champion 77% WP (Copper hydroxide) was against anthracnose only (82.64% disease control). In general, all the fungicide treatments significantly reduced incidence of the diseases and produced higher yield of quality fruits than control in both years.

“…For histopathological studies, 10 mm transverse slices of stems and roots of healthy and diseased tomato plants were preserved in Formalin acetic acid (acetic acid 5%, v/v formalin 10%, distilled water 35% and ethyl alcohol 50%) for the 48 hours (Anjum et al, 2016). For long term storage, fixed samples were then transferred to Acetic ethanol solution (ethanol 75% and v/v acetic acid 25%).…”

“…Fixed stems and roots were sectioned into 3mm transvers portions by freehand sectioning. To prepare permanent slides, the sections were dehydrated through the serial dilutions of ethanol and stained using standard double-staining technique of safranine and fast green stains (Anjum et al, 2016). Real time images were taken with microscope camera after observing under OMAX microscope model G017075953.…”

T omato (L. esculentum L.) is most important and famous fruit vegetable worldwide. It belongs to the family Solanaceae and it was originated from Peru and Mexico (Verma et al., 2018). This fruit is full of nutrients, antioxidants, vitamins A and C; hence, nutritionists recommended its use for managing cholesterol and weight loss (Mj et al., 2017). Ripe tomato fruit consists of various vitamins, amino acid, glucose and fructose. It is a rich source of minerals which include Mg, Ca, P, Fe, Na, K, Cu and S. It also contains protein, fiber and carbohydrates. Tomato has lycopene which is considered as an important component that helps to lower the chances of prostate cancer, heart diseases and age-related diseases (AVRDC, 2003). Tomato is cultivated all over Pakistan due to its high demand. Annually, 599.7 thousand tons of tomato is produced on the area of 63.2 thousand hectares in Pakistan (Akhtar et Abstract | A study was conducted to evaluate the structural and functional modifications in tomato Lycopersicum esculentum nursery seedlings in response to tomato wilt disease caused by fungus Fusarium oxysporum f. sp. lycopersici (FOL). Two months old tomato seedlings were grown under normal conditions in green house and were artificially inoculated with FOL conidial suspension of 1×10 6 conidia/mL by drenching method. Untreated plants served as control. First disease symptoms appeared after seven days of inoculation and seedlings became wilted within 30 days post inoculation. Stems from wilted as well as control seedlings were cross sectioned to observe the histopathological modifications. Wilted cross sections represented the cell wall disintegration and disruption of the tissues along with the blockage in xylem and phloem vessels due to the tylone production. Hyphal growth and proliferated hyphae inside the root cortex were also observed. We concluded that FOL fungus penetrated into the cell wall of the tomato seedlings through hyphae and proliferated into the cortex. Later on, it progressed into the roots and stem, started blocking of the xylem and phloem by producing tylones and deposition of phenolic compounds that supported the FOL to further multiply until the seedlings started wilting and became dead. Moreover, a gradual decrease in shoot height and root length was also observed in the diseased plant as compared to healthy plants.

The mobility and distribution of metals in the environment is related not only to their concentration but also to their availability in the environment. Most chromium (Cr) exists in oxidation states ranging from 0 to VI in soils but the most stable and common forms are Cr(0), Cr(III), and Cr(VI) species. Chromium can have positive and negative effects on health, according to the dose, exposure time, and its oxidation state. The last is highly soluble; mobile; and toxic to humans, animals, and plants. On the contrary, Cr(III) has relatively low toxicity and mobility and it is one of the micronutrients needed by humans. In addition, Cr(III) can be absorbed on the surface of clay minerals in precipitates or complexes. Thus, the approaches converting Cr(VI) to Cr(III) in soils and waters have received considerable attention. The Cr(III) compounds are sparingly soluble in water and may be found in water bodies as soluble Cr(III) complexes, while the Cr(VI) compounds are readily soluble in water. Chromium is absorbed by plants through carriers of essential ions such as sulfate. Chromium uptake, accumulation, and translocation, depend on its speciation. Chromium shortage can cause cardiac problems, metabolic dysfunctions, and diabetes. Symptoms of Cr toxicity in plants comprise decrease of germination, reduction of growth, inhibition of enzymatic activities, impairment of photosynthesis and oxidative imbalances. This review provides an overview of the chemical characteristics of Cr, its behavior in the environment, the relationships with plants and aspects of the use of fertilizers. © 2017, Springer International Publishing Switzerland
