CATASETUMS: Controls, in Increasing Degree of Toxicity to the User Lindane and ethion are equally toxic but lindane is more effective and smaller amounts can be used; it penetrates skin; use disposable rubber gloves. A68-583; OR79-205 0
CATASETUMS: Culture to Get Male or Female Flowers The "Dodson dictum" depends on amount of light exposure received; bright light stimulates female flowers; shade stimulates male flowers. A76-589; A76-605; A76-614The Brubaker system: in addition to light intensity, potting media seem to make no difference; chicken manure's effect unspecified; female flowers may appear under strong light because this is hurtful to them causing hormonal change; well established plants may be female. F69-169+; ODA69-35; ODA70-89 0
CATASETUMS: Dry Period of Rest This is not necessary to induce them to flower; in nature growth is associated with rain and dormancy with dryness; grown warm and watered they often retain their leaves longer; defoliation is often caused by red spider. F69-149 0
CATASETUMS: Eat Buds Greenish and gray worms are probably cabbage loopers; spray with Lannate 90%WP; slight possibility of plant damage from spray. A71-249 0
CATASETUMS: Eat Roots of Cattleyas, Vandas Carbaryl is excellent for control; use 1 ttpg., or one pound in 100 gals, of water; also known as Diocarb. A74-300 0
CATASETUMS: Flower Longevity Many have a short flowering life because of their pollinia triggering mechanism, sometimes set off by hose spray, of such kinds as C. pileatum, C. expansum and their hybrids; those with clustered flowers last up to three weeks; Clowesias and Cycnoches flowers can last up to two months; for breeding details refer to F87-113 0
CATASETUMS: Growth Cycle Vigorous growers, they produce new root systems rapidly; growth can also be rapid with new leaves maturing in a few months, by mid-summer; soon after pseudobulbs swell and inflorescences quickly appear; for details, exceptions, refer to A83-1054 0
CATASETUMS: In Florida Their description and life cycle; six species most frequently found on orchids; no controls given; refer to DK15+ 0

CATASETUMS: With "perfect" Flowers Means "bisexual" flowers with functioning male and female parts; these have recently been transferred in classification to Clowesia and Dressleria; the majority of Catasetums have unisexual flowers which is a highly unique trait in the orchid family. A83-606 0
CATASETUMS: With Unisexual Flowers About 99 species produce male (staminate) flowers and female (pistillate) flowers on the same plant; inflorescences with male tend to be longer, more arching and floriferous, generally the flowers are strikingly different; for further details refer to A83-714 0
