India is the fourth largest country’s production of mustard oilseeds. Mustard oilseeds production 28.6% total oilseeds production. If you cultivated mustard seeds then many pets and diseases attack. How to control mustard pests diseases management is given below-
mustard pests diseases management in India
The larva- yellow-green, and fine erect black hairs scattered all over the body. The adult small grayish brown having pale whitish narrow wings with yellow inner margins. The larvae on the leaves of mustard by making holes. Sometimes they eat up entire laminae of leaf leaving behind the midrib. It also bores into pods and feeds developing seed.
(i) Collection and careful destruction of the larvae at gregarious stages at latest twice a week.
(ii) Spray endosulfan 35EC or malathion 50EC or quinalphos 25EC in 150-200 liters of water/ha.
Aphids are minute with the soft and oval body which is generally pale green or slightly yellow in color. This is a very sluggish insect and does not move much in its wingless form. The insect is abundant from December to March and feeds on various cruciferous oilseeds and vegetable crops. The aphid is a serious pest and the main limiting factor in the production of mustard. Aphid- nymphs and adults suck the sap of the tender leaves, twigs, stems, inflorescence and pods by means of piercing and sucking type of mouth-parts.
(i) The crop is sown before 20th October escape the damage.
(ii) Apply recommended fertilizers.
(iii) Spray dimethoate 30EC or endosulfan 35EC or malathion 50EC in 200-315 liters of water/ha.

Painted bugs(mustard pests diseases management)
The adult bugs are almost spectacular in shape with conspicuous red and orange spots on the body. The males are always shorter than females pest is active from March to December. The full-grown nymphs are about 4mm long, and 2.66mm broad and adults are 3.71mm long, and 3.33mm broad. The nymphs and adults suck cell sap from the leaves and developing pods, and excrete a sort of resinous material which spoils ate pods.
i) Give the first irrigation 2-4 weeks after sowing to reduces the bug population.
ii) Spray endosulfan 35EC or malathion 50EC in 150-200 liters of water/ha.
Mustard Alternaria blight
This is also known as dark leaf and pod spot. The fungus perpetuates through seed and affected plant debris. The pathogen perpetuates through seed and affected plant portion in the soil. During the severe outbreak, pods turn black in color and may also rot. Such pods contain shriveled, undersized seeds.
(i) Grow resistant varieties like YSPB-24 ( mustard variety details)
(ii)Spray Mancozeb 75WP or Blitox in 250 liters of water/ha.
Mustard Downy mildew(mustard pests diseases management)
Downy mildew is a serious disease in mustard. It is caused by the fungus. Downy mildew can affect plants of all ages. Fast symptom appears as small yellow spots or water-soaked lesions on the topside of older leaves, then the result is photosynthetic area caused stunting of plants, reduced yields, of the fruits following defoliation.
(i)Consider washing equipment and tools before moving the field to another.
(ii) Spray Mancozeb 75 WP in 2gm/liter of water.
Mustard white rust
These pustules are raised blisters found on the leaves, stems and floral parts. Floral parts are much deformed. The petals become green and stamens are transformed into a leaf-like structure which becomes thick and club-shaped. The disease becomes more serious if it occurs along with the downy mildew.
(i) All crop refuse should be destroyed carefully after harvest.
(ii) When symptoms are noticed then Spray Blitox or Mancozeb 75WP 250 liters of water/ha.
Mustard powdery mildew(mustard pests diseases management)
Small discrete white patches develop on both leaf surfaces. Patches coalesce until a powdery mass of white mycelium and spots cover the entire leaf. The leaves later become yellow, then brown, and prematurely defoliate.
i) Avoid drought stress.
ii) If you continue 3 years cultivated then crop rotation is the best method.
iii) Spray Karathane(0.2%) at 10 days interval starting from the first appearance of the disease.
