SAFETY : TOMATOES BEST FRIENDS
Tomato is one of the most important vegetable worldwide. Tomato is one of the most important “productive food” because of its unique nutritive value. It is one of the most versatile vegetables with administered usage in India culinary tradition. As it is a relatively short duration crop and gives a high yield, it is economically attractive, and the area under cultivation is increasing daily.
Soil and climate requirements for Tomato:
It is a warm season crop and requires a relatively long growimg season with plenty of the sunshine and moderate day temperature of 20-28 degree. It is sensitive to frost. Low temperature, restricts the plant growth and fruit setting is low . The critical factor in the establishment of fruit is the night temperature, the optimum range being 15-20 degree. The red pigment in the fruit will develop only when the temperature is between 15-30 degree. Above this range of temperature, only the yellow pigment formed. If the temperature exceeds 40 degree, no pigments are formed. Tomato can be grown in all types of soils, but the soil should be friable. However, it grows best in light soils ranging from sandy loam to loam.
Hermful fungi: There are some hermful fungi that affect the crop.
1 Alternaria solani: Alternaria solani is a fungal pathogen, that produces a disease in tomato and potato plants called early blight. The pathogen produces distinctive “bullseye” patterned leaf spots and can also cause stem lesions and fruit rot on tomato. The appearance of circular or irregular dark spots on the lower, more mature leaves is one of the first symptoms of infection. Eventually, the spots enlarge into a series of concentric rings surrounded by a yellow area. The entire leaf may be killed and will drop off the plant. Early blight can result in extensive defoliation, exposing fruit to sunscald and reducing yields. This disease typically progresses from the base of the plant, upward.
2 oomycete Phytophthora infestans: Phytophthora infestans is an microorganism, specifically an oomycete, which causes the serious potato and tomato disease known as late blight or potato blight. Late blight is a potentially devastating disease of tomato a, infecting leaves, stems, and fruits of tomato plants. The disease spreads quickly in fields and can result in total crop failure if untreated.
Signs and symptoms :
1 Leaves have large, dark brown blotches with a green gray edge; not confined by major leaf veins
2 Infections progress through leaflets and petioles, resulting in large sections of dry brown foliage
3 Stem infections are firm and dark brown with a rounded edge
4 Firm, dark brown, circular spots grow to cover large parts of fruits. Spots may become mushy as secondary bacteria invade
5 In high humidity, thin powdery white fungal growth appears on infected leaves, fruit, and stems
6 In cool, wet weather, entire fields turn brown and wilted as if hit by frost
We at HPM India, are endeavoring to focus on the cure to fungus and soil borne diseases in crops. Tomato products can be truly influenced by these two destructive elements, especially in warm and wet atmospheres. It is vital to screen the harvests frequently and act rapidly if any malady manifestations are watched. Disease might be caused because of soil tainting or different growths. For fungi related yield harm, HPM India offers viable arrangements and some of them are extremely strange and accompanied extra advantages to crops.
SAFETY (Mancozeb 35% SC) :
Safety is a broad-spectrum fungicide with protective action. It has a suspensibility of more than 90% means negligible sedimentation in spray tank and provides more leaf coverage and also results in uniform distribution of particles on plant surface. It is preventive fungicide, it is better to spray before disease appears/at the initiation of the disease. General application rate for foliar spray is 500 g/100 liter of water. Water Volume ranges between 200-400 liter per acre, based upon crop type and crop stage.
It is used to controls Early and Late bight of Tomato.
