COTTON
The spray of microbial insecticides Lecanicillium lecanii (2 x 108 cfu/g -1% WP) or Beauveria bassiana (2 x 108 cfu/g - 1% WP) @ 40 g /10 litre water at fortnightly interval for three times starting from initiation of sucking pests is advised for the effective biological control of sucking pests infesting Bt cotton.
Raising of 10 per cent maize plants randomly or one row of cowpea in-between two rows of cotton is advised to reduce the population of jassid and whitefly and increase the population of biocontrol agents in Bt cotton.
Adopt following measures to enhance the activity of natural enemies and thereby to suppress the incidence of insect pests in cotton Hybrid-10.
Interspersing of one row of Cassia occidentalis L. after every six rows of cotton and sowing of maize and planting of Zinnia (Zinnia elegans) @ 10% of total population of cotton plants
OR
Interspersing of one row of Cassia occidentalis L. after every six rows of cotton, sowing of maize and planting of Zinnia (Zinnia elegans Jacq.) @ 10% of total plant population of cotton plants and one release of Trichogramma chilonis @ 1.5 lakh/ha + Chrysoperla carnea @ 5000 larvae (2-3 days old)/ha, coinciding with the appearance of pests.
Note: Cassia occidentalis should be harvested before ripening of the pods.
For the management of pest complex and to conserve entomophage diversity in cotton Hybrid-10, adopt the following IPM package.
1. Hand picking of different stages of pests and putting them in 60 mesh wire screen cages twice during peak incidence.
2. Interspersing of 10% maize plants with cotton crop, sowing of cotton and maize should be done simultaneously.
3. One release of Chrysoperla carnea @ 14,000 larvae (2-3 days old) synchronizing with the appearance of the pests.
4. Release of Trichogramma chilonis @ 1,50,000 per hectare per week (5 releases), first release should be synchronized with the appearance of the bollworms.
Sucking pests of cotton hybrid-6 can be economically (ICBR 1:4.07) and effectively managed and natural biological control agents are conserved by implementing following Integrated Pest Management module in middle Gujarat.
Cotton bollworms i.e. Earias vittella and Heliothis armigera can be satisfactorily controlled by supplementary release of Trichogramma chilonis and T. achaeae (Both @ 10,000/acre). Release of Chelonus blackburni @ 5000/acre, Chrysoperla carnea 100 adults per acre and Rogas aligarhensis 150 adults/acre at fortnightly interval and by spraying purified suspension of indigenous NPV of Heliothis armigera @ 109 PIB/ml at 3 days interval. Since Spodoptera litura Fab. often infest cotton, spraying of purified suspension of NPV of S. litura in the evening immediately after the occurrence of the pest is recommended.
PADDY
Spraying of Bacillus thuringiensis (5 x 107 spores/mg) @ 1.0 kg/ha (20 g/ 10 litre water) or Beauveria bassiana (2 x 106 cfu/g) @ 1.0 kg/ha (20 g/ 10 litre water) or Lecanicillium (Verticillium) lecanii (2 x 106 cfu/g) @ 1.0 kg/ha (20 g/ 10 litre water) is advised at initiation of leaf folder damage in paddy.
The paddy growers are advised to use resistant paddy cultivar (Gurjari), transplanting of paddy seedlings during first fortnight of July and application of NSKE 5% (500 g/ 10 litre water) to suppress the incidence of leaf folder and maintain the population of predatory spiders.
MAIZE
Application of Bacillus thuringiensis NBAIR strain – Bt G4 (1% WP - 2x108 cfu/g) @ 50g/10 litre water or Bacillus thuringiensis AAU strain -AAU Bt1 (1% WP - 2x108 cfu/g) @ 50g/10 litre for three times at ten days interval with the initiation of the pest found effective for the management of fall armyworm Spodoptera frugiperda in maize
PIGEONPEA
Application of talc-based mixture of Trichoderma harzianum (108 spores / g) @ 5 kg/ha + Pochonia chlamydosporia (108 spores/ g) @ 20 kg/ ha in furrows at the time of sowing for effective management of cyst nematode, Heterodera cajani in pigeonpea.
CHICKPEA
For the management of pod borer and wilt in chickpea, following Bio-Intensive Pest Management module can be adopted.
1. Seed treatment with Trichoderma viride (2 x 106 cfu /g) @ 8 g /kg seed at the time of sowing against wilt disease.
2. Use of FYM @ 1 ton/ha enriched with T. viride (2 x 106 cfu /g) (2 kg/ ton of FYM) for wilt disease.
3. Planting marigold (Tagetes erecta) on the borders of chickpea field as trap crop for Helicoverpa armigera.
4. Installation of pheromone traps @ 40 traps/ha at 15 days after sowing for trapping of H. armigera male moths.
5. Installation of “T” shaped bird perches @ 100 /ha at 15 days after germination.
6. Alternate spray of HaNPV @ 250 LE /ha and Neem Seed Kernel Extract @ 5% during vegetative stage, at flowering stage and at pod formation stage for the suppression of H. armigera.
Spraying crude suspension of an indigenous NPV of H. armigera @ 100 L.U. in 350-400 litres of water/acre/week effectively control the H. armigera infesting chickpea.
BRINJAL
Spraying of cow urine 20% fortified with leaf extract of either neem, custard apple, lantana or jatropha 10% (1 kg/10 litre water) for suppression of sucking pests (aphid, leaf hopper and whitefly) as well as shoot and fruit borer in organically cultivating brinjal.
TOMATO
Spraying of HaNPV (1.0x109 POB/ml) @ 250 ml/ha (5 ml/ 10 litre water) or Beauveria bassiana (1x 108 cfu/g) @ 1.0 kg/ha (20 g/10 litre water) or Metarhizium anisopliae (1 x 108 cfu/g) @ 1.0 kg/ha (20 g/10 litre water) at 85 days after transplanting suppress fruit borer, Helicoverpa armigera infesting tomato.
Spraying crude suspension of an indigenous NPV of H. armigera @ 100 L.U. in 350-400 litres of water/acre/week effectively controls the H. armigera infesting tomato.
OKRA
The spraying of Bacillus thuringiensis var. kurstaki 1% WP @ 50 g/10 lit. water or NSKE 5% (500 g/10 litre water) at fifteen days interval for three times or six releases of Trichogramma chilonis @ 50,000/ha at weekly interval starting from the initiation of shoot and fruit borer (Earias vittella) is advised for the effective control of the pest in okra.
Below mentioned Bio Intensive Pest Management module is advised for the management of pests of okra.
CABBAGE
Two sprays of Beauveria bassiana (2 x 106 cfu/g) or Lecanicillium (Verticillium) lecanii (2 x 106 cfu/g) @ 30 g/10 litre water at the initiation of pest incidence for suppression of aphid and head borer (Helicoverpa armigera).
