(iii) Research Achievments


A schedule for the management of three rusts of wheat has been developed. Three to four sprays of Zineb (Dithane Z-78 @ 0.25 per cent) now replaced by more effective Dithane M-45 (@ 0.25 per cent) at an interval of ten days from the time of initial outbreak of disease has proved to be effective in reducing the rust incidence. Bayleton (@0.25 per cent), a systemic fungicide, was effective in reducing the disease intensity of black and brown rust from 13 to 100 per cent.

Zinc sulphate (50 kg/ha) alongwith normal dose of NPK (120:60:40) as basal application reduced incidence of the rusts and black point diseases in wheat.


Ear-cockle (Angunia tritici) appeared in epiphytotic form at a village Paloi, district, Panna during 1998. It was eradicated by the replacement of seed lot.



Occurrence wise important diseases of chickpea are wilt (Fusarium oxysporum f. sp. ciceri), collar rot {Sclerotium rolfsii) and dry root rot (Rhizoctonia bataticola). Since these diseases are mainly soil borne in nature, emphasis was given to manage them through host resistance, cultural practices, biocontrol agents and seed treatment.

Integrated disease management

Genotypes viz., JG 315, JG 74, JG 322, JG 11, JG 130, JG 16, JAKI 9218, JG 63, JG K1, JGK 2 ,JG 12, JG 14 possessing resistance to wilt have been released. Varieties JG 11, JG 130, JG 63, JG 2003-14-16, JG 89-11551, JG 89-9032 are tolerant to dry root rot also while JG 16 has tolerance to Collar rot Stunt and Botrytis grey mold . JG 12 and JG 24 are recommended as doner parent for wilt at National level.

The wilt disease was checked by seed treatment with Trichoderma harzianum, T. viride, Bacillus subtilis or Pseudomonas fluorescence or Viride+ Carboxin @ 4:1 g/kg seed. on less susceptible variety.

Intercropping of chickpea + linseed (4:1 row ratio) could reduce the chickpea wilt significantly with increase in chickpea yield. Sowing dates have been found to greatly influence chickpea wilt and collar rot incidence. Accordingly, it is recommended to sow the crop after first week of November. Deep ploughing in summer, using resistant variety, seed treatment with benomy1 + thiram (1:3) @ 3kg/kg seed or carbendazim @ 2g/kg seed and sowing chickpea in last week of October or first week of November reduces the wilt incidence.

Fusarium isolates were characterized and found 5 races i.e. 2,4,5 and 2 more new in the state .


Wilt (Fusarium udum) is the major disease problem of pigeonpea while Phytophthora blight {Phytophthora drechsleri f. sp. cajani) occurs in pockets where rainfall is high and field drainage is poor. Stem cankers caused by Phoma cajani, Macrophomina phaseolina and Xanthomonas cajani occur commonly but do not cause much damage to the crop.

Integrated Disease Management:
Host resistance identified in cent percent wilt sick field, studies conducted on influence of fungicidal seed treatment and soil amendment on the development of Fusarium udum propagules in soil and wilt incidence concluded the treatment of seeds with Benlate +Thiram (1:3) and amending the soil with crop residues of oats is an effective method for the management of pigeonpea wilt.

Phytophthora Blight

The disease occur in all the pigeonpea growing areas of M.P. causing considerable losses especially in poorly drained fields. Genotypes KPBR 80-2-1, KPBR 80-2-2. ICP 9252, KPBE 80-3, KPBR 80-1, T-7, AGS 522, ICPL 161, ICPL 8863, PR 5149 Selection. P.I. 397430 Sel., ICP 7065 and ICP 7250 were found resistant to disease in the sick plot over the years.

The disease can be managed by integrated methods ridge sowing + seed treatment with Apron 4g/kg + soybean as cover crop + tolerant pigeonpea variety

The resistance was found in genotypes KM-34 against Heterodera cajani, Meloidogyne incognita and Meloidogyne javanica KM-9, KM-29 and KM-61 to Meloidogyne incognita and Meloidogyne javanica, Nematodes have not been proved as a constraint in low yields of pigeonpea. Pigeonpea genotypes developed at the Research Station in ICAR Pulse Project was identified as resistant to KM-34 to H. cajani, M.incognita and M. javanica while KM-9, KM-29 and KM-61 were resistant to M.incognita w AM.javanica


The important diseases of lentil are wilt (Fusarium oxysporum f. sp. lentis), collar rot (Sclerotium rolfsii) and rust (Uromyces fabae) may become serious if winter rains occur in January -February. Major work was done under PL 480 scheme on 'Lentil wilt' and has been reviewed by Agrawal and Prasad (1997). Since good resistance source to wilt and collar rot in bold seeded lentil are rare. Efforts were made to findout other methods of control.

The disease can be reduced by seed treatment with thiram + carbendazim (1:1) @ 2.5 w/w and application of phosphatic fertilizer,

Mung and Urdbean

The major problems of these crops are foliar diseases especially powdery mildew (Erysiphe pisi), anthracnose (Colletolrichm dematium), leaf blight (Macrophomina phaseolina) and leaf spots (Cercospora sp., Protomycopsis sp). These pathogens are seed borne.

Continuous cropping of urdbean in a field showed increased intensity of leaf blight, seed treatment with carbendazim (1 g/kg) reduced seed and seedling mortality, leaf blight phase of the disease and increased yield significantly.


Research work on soybean pathology was initiated at Jabalpur when the crop was introduced in 1966-67.More than 25 pathogens/diseases have been reported to occur in soybean in M.P. but only ten, viz., Rhizoctonia solani, Sclerotium rolfsii, Macrophomina phaseolina, Myrothecium roridum, Xanithomonas axonopodis pv. glycines, Phoma sp., Colletotrichum truncatum, Alternaria spp, bud blight like syndrome and yellow mosaic are of major importance.

A number of pathogens attack the emerging seedlings like Sclerotium rolfsii, Rhizoctonia solani and R. bataticola causing heavy losses.

Seed treatment with thiram + carbendazim (2:1) @ 0.3per cent and reduced these diseases, improved the emergence by 25 per cent and yields by 2-3 q/ha.

Besides resistant genotypes two sprays of streptocycline (@ 0.02per cent) + Copper oxychloride 50 WP (@ 0.2 per cent) were effective in reducing bacterial pustul disease.

Two sprays of hexaconazole 5 EC or propiconazole 25 EC or triadimefan 25 WP @ 0.1 per cent reduced the rust severity by 35 per cent. Varities JS 80-21, Indira soy 9, PK 1024, PK 1162 were moderately resistant to rust.

Rapeseed - Mustard

White rust, Alternaria blight and Sclerotinia stem rot are the major diseases of rapeseed mustard.

Two new races of Albugo candida, race 12 from Brassica juncea and race 13 from B. rapa var. toria were identified.

The effect of temperature on viability of zoosporangia of Indian isolate of A. candida from B. juncea revealed that they remained viable up to four days at 20°C and for 2 days at 25°C while Canadian isolate (race-2) remained viable only for 3 days at 20"C

A number of rust resistant lines, such as JMMWR 93-37, 93-38, 93-39, 941-l-2and JYM-1 were developed, out of which JMMWR 93-39 was notified as Jawahar mustard-1.

The resistant cultivar exhibited higher amount of potassium content ranged from 3.15 to 3.52 mg/g tissue than susceptible one (2.86 to 3.11). Similarly, there was significant decrease in sodium and potassium content after disease development. The disease increased with high humidity (for 96 hrs), closer spacing (5 cm), and delayed sowing (5th August).

Commercial crop



Mainly smut was observed, which appeared from first week of May - June and no fresh infection occurred during July to August and again noticed during September to November.

Set treatment with carbendazim or mancozeb or moist hot air treatment of sets at 54°C for 4 hrs. were effective in checking the set-borne infection of smut enhancing the germination Planting of crop in November and December had minimum smut incidence


Fusirum moniliforme and F. oxysporum were associated with diseased plants. The incidence of this disease varied from 9-20per cent in planting and 13-35per cent in ratoon crop.


For management of stem necrosis early planting (October) and three sprays of monocrotophos 40 EC @ 1 ml/lit. at an interval of 15 days are recommended. Early blight of potato can be successfully controlled with prophylactic spray of dithane M-45 @ 2 kg/ha. Black scurf disease of potato can be controlled by seed treatment with bavistin (0.2 % ) dipping seed for 30 min in fungicidal suspension.

Haulm cutting in the first week of January gave control of early blight, late blight, leaf curl, mosaic and stem necrosis of potato.


‘Ginger yellows’ apparently perpetuated through infected rhizomes and temperature ranging between 23-290C accompanied with 95 per cent RH. The disease is managed by treating the seed rhizome with benlate (0.25per cent) or dithane M-45 (0.3per cent) solution for 1.5 to 2 hours followed by two drenching at an interval of 20-25 days @ 6 litres/m2 with the same concentration by either o the above fungicides.

Medicinal crops

Aswgandh (Withania somnifera)

Seed treatment with Trichoderma harzianum + Carbandazim or Trichoderma viride alone significantly reduced the seed and seedling mortality caused due to soil borne fungi. Alternaria leaf blight of Asgandh is effectively controlled by spray of Mancozeb @ 2.5g/L or Cumin L @ 3 ml/L.

Isabgol (Plantago ovate)

One spray of metalaxyl 72 MZ @ 0.2per cent + two spray of Dithane M-45 @ 0.3per cent were most effective in reducing the disease incidence (18per cent ) as against 38.23per cent in control and increasing seed yield 8.75 q/ha..

Seed treatment with T. viride + 35 WS and soil application with T. viride done after 20 days of germination significantly reduced the per cent root rot and seedling mortality.


Purple blotch of garlic was effectively controlled by Rovrol. (0.3%).


Seed treatment with Trichoderma harzianum @ 10 g/ml. + Bavistin @ 0.1per cent and Trichoderma viride alone significantly produced higher yield.
