Use of Progibb in Potato Cultivation Area of Punjab

Potatoes (Solanum tuberosum) are an important high-value commodity for producers in the Punjab Region. Intensive fertilizer management is necessary in loamy soils to ensure proper nutrient supplies to growing crops. Such soils generally have overall low organic matter, low cation exchange capacities, and low total nitrogen (N) in the upper horizon, which means that little N is mineralized from soil organic N sources and N must be applied with fertilizer to match crop uptake needs. Generally, only 1 to 3% of total organic N concentrations in the soil become available to a crop within the growing season. Nitrogen management is one of the most important aspects for potato production. Tuber deformity and secondary growth are historically correlated with moisture; however, other environmental factors that initiate and decrease growth, such as N fertility, may also be a cause.

Nitrogen application timing is one of the most important management techniques that producers can use to increase their fertilizer N use efficiency. Fertilizer should be split between at planting, at dragoff (approximately 30 days after planting when potato plants are beginning to emerge, are bedded during cultivation, and the bed height is reduced), and immediately prior to bloom. Split N applications are recommended to increase overall yield and fertilizer use efficiency. However, N applications too late in the growing season can significantly delay maturity and decrease tuber quality. Nutrient availability is not only important for overall yield in potato production, but is also important for disease management. Fertilizer applications can significantly impact both foliar and tuber disease. Growth regulators have been researched for decades to help producers manage tuber sugar content, maturity, and sprouting after harvest and during storage. However, results are mixed depending on the factors studied. In conclusion, N rate has the greatest impacts on deformity, tuber rots, and yields for potatoes. 

Gibberellic acid (GA) is applied to potato tubers cultivated from true seed (TPS) either by immersion of intact tubers in aqueous solutions, or by the excision of a small area of the tuber close to the point of detachment from the stolon and immersion of this region only in GA. Corresponding treatments with deionised water were used as controls. Tubers that had been treated with GA broke dormancy earlier than the controls, especially when the tubers were cut prior to treatment. Dormancy breakage correlated with higher weight loss and an increase in the rate of respiration of tubers following sprout emergence. The optimum time of immersion in GA to achieve dormancy breakage was 2 h, irrespective of GA concentration over the range tested (1–50 mg L⁻¹). The bisection of tubers at various times after GA application to the point of detachment from the stolon indicated that GA movement longitudinally within the tuber was necessary for it to have an effect on sprouting. GA did not affect the rate of ethylene production by the tubers, but increased starch breakdown and α-glucosidase activity in the bud, as well as the RNA content, especially at the sprout apex, prior to sprouting.

Valida - The Shield Against Potato Diseases

Sumitomo Chemical has successfully addressed the problems faced by the potato cultivators of Punjab. There has been an increase in the incidence of the black scurf of potato. Punjab alone, has witnessed an increase in incidence of this disease by 12% as compared to the last year. The disease commonly affects the tubers, sprouts, stems and stolons. The most common symptom is black scurf comprising of dark brown to black irregular lumps sticking on the surface of tubers. These irregular lumps are closely adhered to the tuber surface and do not wash off easily. Other symptoms on the tuber include skin cracks, crater like depressions, pitting, stem-end necrosis and shape deformity. The disease often causes sprout injury both in storage and in fields after planting. The affected sprouts show discoloration of tissue. The heavily infected sprouts cannot emerge from soil leading to gappy germination.The emerging sprouts when infected later develop cankers causing girdling of stem bases. Such affected plants show upward rolling of leaves with pinkish or purplish margin. Often small green or reddish aerial tubers are also formed in the axils. The infection also spreads to roots and developing stolons resulting in rotting of cortical tissues. Such infected roots later shed away hence infected plants have poor root system. Infected stolons give rise to deformed tubers.

Till date the following chemicals are used for the control of black scurf in potato:

• Emison + Carbendazim
• Boric Acid + Carbendazim
• Monceron

Sumitomo Chemical introduces a new product "Validacin" to combat this deadly disease. Validacin is a Japanese product meant for Rhizoctonia solani. It is different from other products available in the market because it is systemic in nature, while others are contact in nature. Validamycin 3% L is both systemic fungicide and antibiotic. It is the best solution for control of Rhizoctonia fungus.

Key features:

• Lesser cost as compared to existing
• Longer effect
• No residue in crop as well as soil
• Bio Pesticide & Eco Friendly
• Non Toxic to beneficial insects & Human
• Real Natural Systemic fungicide and Antibiotic

Validacin pricing:

• Market Price: Rs. 500/ltr
• QUANTITY DISCOUNTS –10 RS ON 1000 LTRS.                                                                                                  –20 RS ON 2000 LTRS.

Mode of action:

The chemical is absorbed by the cells of the pathogenic fungus as nutrilite and transmitted through the hyphae (filaments which constitute body of fungus), whose growth is affected as soon as the contact with the active ingredient is established. This makes the hyphal top abnormal and inhibits the growth of the hypha through inhibiting the synthesis of inositol which is the essential for the growth of the fungi.

Comparison:

Method of application:

1. As a spray: 250 ml per pump Validacin spray on 6-7 Qtls potato, change the side and then spray once more with the new solution of same dose and dry it in shade.

2. As a dip: 250 ml per 100 Ltr of water dipping for 6-7 Qtls and dry it in shade. 

How is an antibiotic an Edge with Validacin?

> Antibiotics are chemicals that are used to treat infections caused by bacteria and other organisms like parasites, and fungi e.g. Streptomycin.

> They either kill bacteria or keep them from reproducing.

> Chemical substance that in dilute solutions can inhibit the growth of harmful microorganisms also.

So with Validacin we are having an edge of Systemic on all the existing contact fungicide as well as of Antibiotic too.

Sumitomo Chemical combats diseases in potato

Sumitomo Chemical, a renowned agro-chemical company, has always had an upper hand in creating awareness among the farming community of India. It has shown its presence in the Punjab region too. Sumitomo Chemical company is now educating the farmers of Jalandhar, focusing mainly on the potato cultivators of the region.

The main disease of the region being the black scurf caused by Rhizoctonia solani, was highlighted by the company. 

The following are the symptoms of the disease:

• Black speck, black speck scab, russet scab on tubers

• At the time of sprouting dark brown colour appear on the eyes

• Affected Xylem tissue causes to wilting of plants

• Infected tuber contains russeting of the skin

• Hard dry rot with browning on internal tissue

• Spongy mass appear on the infected tuber.

• Seed tubers are source of spread

• Moderately cool , wet weather  and temp 23 °C are the favourable for the development of disease

About pathogen:

The mycelium is hyaline when young and brown at maturity. Hyphae are septate and branched with a characteristic constriction at their junction with the main hyphae. The branches arise at a right angle to main axis. Sclerotia are black. A basidium bears four sterimata each with a basidiospore at the end. The basidiospores are hyaline, elliptical to obovate and thin walled. They are capable of forming secondary basidiospores.

Mode of spread and survival:

The fungus is capable of leading a saprophytic life on the organic material and can remain viable in the soil for several years. The sclerotia on the seed tubers is the principal source of infection of the subsequent crop raised with these tubers. On return of favourable conditions the mycelium present in the soil may develop producing new hypae.

Management:

Disease free seed tubers alone should be planted. If there is a slight infection of black scurf in the harvested potatoes it can be controlled by spraying 250 ml per pump Valida spray on 6-7 quintals potato, change the side and then spray once more with the new solution of same dose and dry it in shade or dip them in 250 ml per 100 Ltr of water dipping for 6-7 quintals of potato and dry it in shade.
