NEW CLAIMS
For the control or suppression of green mirids, silver leaf white fly (biotype b) and heliothis in cotton and suppression of diamondback moth in brassicas as specified by the Directions for Use table.
Also for use in cotton for the reduction in formation of the microsclerotia of Verticillium dahliae assisting in the management of Verticillium wilt.
APVMA Approval No:
81070/126360


WHY DOES IT WORK?
Butterfly Pea cyclotides are chemically diverse – the genome of Butterfly Pea has been mapped with over 60 Cyclotide sequences having now been observed with 39 new cyclotides having been discovered during the process.
Butterfly Pea organs express different cyclotides
When we test extracts from different organs:
- Those from aerial parts interact with insect-like membranes to disrupt them and inhibit microsclerotia development of verticillium dahliae
- Those from parts that contact soil are effective against early-stage nematodes
- Work continues to identify the specific cyclotides responsible for fungicidal activity
WHAT HAS BEEN DONE?
- Replicated laboratory assays began in 2016-17 – these assays demonstrated suppression of microsclerotia at all rates, whether applied to plates as a spray or drench.
- Replicated field trials commenced 2017-18 – applications were in different regions and were
targeted to prevent microsclerotia developing in infected plant tissue.
These field trials were conducted by Dr Karen Kirkby and team at NSW DPIE over 2 seasons and across 2 valleys. The data presented here is a summary of Dr Kirkby’s work.
Foliar sprays were applied at intervals by a ground rig or by aircraft to foliage
- December or when majority of plants are between first square and first flower.
- February or when majority of plants are between mid to late flowering.
- March or with first defoliation.
Measurements of inoculum levels (propagules per gram) were taken pre-plant and again during the growing season and post-harvest.


WHAT WILL IT DO?
In seasons where PPG significantly increases Sero-X will limit the increase and in season where there would be a natural reduction, Sero-X can speed up the reduction by limiting the amount of infected tissue returning to the soil.

TRIAL CONCLUSIONS
Field and laboratory trial data confirm that Sero-X Pesticide containing 400g/L Clitora ternatea extract, provides effective suppression of microsclerotia of Verticillium dahliae in cotton and would assist in management of verticillium wilt as an alternative to crop rotation.
