A field trial was conducted in Argentina to determine the effect of blending codling moth pheromone, (E,E)-8,10-dodecadien-1-ol, with chlorantraniliprole for control of coding moth population in apple orchards. The first flight of codling moth was targeted, at which time standard grower treatment pheromone dispensers had been placed in the respective fields. Applications of the chlorantraniliprole or chlorantraniliprole+pheromone were timed when eggs were expected to hatch.
Treatment programs comprising nine tracts of land across three farms were performed (see
aadministered via 90 dispensers per hectare, including dispensers placed at orchard borders.
In brief, one treatment program was performed using an application of pheromone alone at 90 DD followed by applications of chlorantraniliprole plus pheromone at 250 DD and 250DD+21 days, respectively. A separate treatment was performed by applying chlorantraniliprole alone at 250 DD and 250DD+21 days. A third treatment was performed by applying the standard grower treatment of pheromone (Cidetrak® CM Meso in dispensers) at 90 DD followed by applications of acetamiprid at 250 DD and phosmet at 250 DD+14 days and 250 DD+28 days.
Treatment effects were determined by conducting fruit damage counts prior to second generation flights by evaluating 1000 fruit in each plot for codling moth damage. 100 trees were banded with 8 cm width bands of corrugated cardboard (one per trunk) in order to trap 5th instar codling moth first generation larvae as they crawl on the tree in search of a place to pupate. The bands were removed during the second week of January, taken to the lab and counted.
All treatments resulted in good control of codling moth damage at end of overwintering generation flight, as shown in
In the trial having the highest infestation of codling moth (Trial 4 of
In summary, this study showed that addition of codling moth pheromone to chlorantraniliprole significant and unexpectedly improved control of codling moth compared to applications of (1) chlorantraniliprole alone; and (2) a combination of pheromone and acetamiprid/imidan, which is the grower standard in Argentina for apple crops.
A field trial was conducted in Argentina to evaluate the efficacy of chlorantraniliprole in combination with a kairomone, ethyl (2E,4Z)-2,4-decadienoate, to improve Cydia pomonella control in foliar application of apple (Malus domestica) compared to the efficacy of chlorantraniliprole alone and kairomone alone. The treatment protocols are shown in Table 4. SC=suspension concentrate; CS=capsule suspension
Efficacy of the trial was evaluated by (1) comparing the number of damaged fruit across the treatment groups; and (2) comparing the larva captured per hectare that were captured from corrugated cardboard traps settled in 100 trees. As shown in
In summary, this field trial showed that all doses of chlorantraniliprole+kairomone were effective to reduce Cydia damage on fruits and all doses of chlorantraniliprole+kairomone were effective in the reduction of Cydia pomonella population based on the number of larva captured in corrugated cardboard traps. In addition, all doses of chlorantraniliprole+kairomone showed better performance than just applying chlorantraniliprole in reducing fruit damage, and chlorantraniliprole+kairomone (7 mL c.p./hl+1 mL c.p./hl) showed significantly better reduction in the number of captured larva compared to chlorantraniliprole treatment applied with no kairomone.
