Embodiment 1

[0145] Example 1 - Apple - cv Elstar

[0146] Examples of TAMPF formulations in these experiments included AN+AC+ADD applied at a rate of 1 liter per hectare. ADD: at least one of category (f), each <3 g / l, and at least one of category (c).

[0147] A. Apple, cv ELSTAR. Spray (single application) 11 June with an average fruit diameter of 20 mm. Count in July.

[0148] Number of fruits per branch (average of two branches per tree)

[0149] T = tree, B = branch (ie, representative position of the count).

[0150]

[0151] The results show effective fruit thinning of TAMPF formulations.

[0152] B. Apple cv Elstar - follow-up results.

[0153]

[0154] TAMPF formulations showed less fruit set per shoot, improved skin quality (reduced rust), less fruit per tree at harvest and higher average fruit weight (g) at harvest relative to untreated. Good fruit thinning occurs which leads to improved weight per fruit.

[0155] C. Apple cv Elstar - follow-up results.

Embodiment 2

[0166] Example 2 - CHRYSANTHEMUM - cv Herby Blend

[0167] A. Demonstration of the benefit of application of auxin / auxin precursor or auxin / auxin precursor and paracetamol on bud thinning.

[0168] Growth details: Plants were sown in commercial seed compost and then "pricked out" into professional grade all purpose compost in 9 cm pots in a randomized block design. Provide at least 10 hours of general daylight and supplemental lighting per day. Heat to maintain a minimum of 60 degrees Fahrenheit during the day and 40 degrees Fahrenheit at night.

[0169] Sowing date: October 5, 2009, seedling plug. Date of application: December 2, 2009 (the first bud). Measurement date: January 12, 2010 (flowering). Measurement: Buds per plant.

[0170] Apply a number of auxins or auxin precursors, 10 each -2 Molar concentration solution. In each trial, 3 g per hectare equivalent of paracetamol (AC) was added.

[0171]

[0172] Application of an auxin or an auxin precursor resulted ...

Abstract

A composition comprising a compound selected from an auxin, an auxin precursor, an auxin metabolite or a derivative of said auxin, auxin precursor or auxin metabolite or a mixture thereof and acetaminophen or a derivative thereof for is used as a chemical thinning agent.

Description

field of invention [0001] The present invention relates to methods and compositions for reducing the number of fruit and / or flowers on a plant by treating the plant with, in particular but not exclusively, anthranilic acid, optionally in combination with paracetamol, or an auxin in combination with paracetamol . Background of the invention [0002] Many plants produce more fruit than would be desirable to produce high quality fruit. Thinning of fruit or flowers that can lead to fruit prevents the above-mentioned overproduction and can promote successive years of fruiting. Fruit thinning can also increase fruit size, improve fruit color, and increase plant vigor. [0003] Hand thinning fruit is very expensive and labor intensive. Therefore, there is a strong need for effective chemical fruit thinners. In some cases, existing chemical thinners are ineffective and can be dangerous due to under- or over-thinning of fruit. [0004] Naphthaleneacetic acid (NAA) is a commonly ...
